Strengthening 【Outline of research achievement 】
Properties of fluidity and segregation resistance of fresh concrete were studied with the aim to improve the high quality and durability of concrete structures. Experimental study was conducted in consideration of the factors: distance from vibrator to re-bars and the water/cement ratio. It was revealed from experiments and sampling cores and the distribution of coarse aggregates measured by using AE method that the distance from vibrator to re-bars and the viscosity related with water/cement ratio affect the fluidity of concrete and the homogenization of cover concrete. Also, it was cleared from the pore size distribution of surface of concrete that the quality and durability of steam-cured pre-cast concrete were improved with the sprinkling water under steam cure process. Further, the strengthening mechanism by using CFRP grid and sprayed mortar for deteriorated existing concrete and the calculation method for load carrying capacity were investigated through some experimental tests. 【Presentations 】

【Department 】：Department of Civil and Environmental Engineering, School of Urban Environmental Sciences 【Name 】：Akira KAWAMURA 【Position 】：Professor 【Research Topic 】：Hydrology, Water Resources Engineering 【Outline of research achievement 】 1) A social sustainability assessment framework of groundwater resources with a focus on Hanoi is proposed for the first time. We proposed 3 main aspects (quantity, quality, and management) and appropriately selected their 13 sustainability indicators for this target area. We introduce a sustainability index function (SIF) for indicators to clarify the relationship between each indicator value and its sustainability index. 2) We presents the reproducibility analysis of the distribution hydrological model using several rainfall data, such as XRAIN and ground observation rainfall data, applied to the upper basin of Kanda river in Tokyo. The highest reproducibility is observed by using high density deployed ground observation rainfall, among the simulation using other rainfall data including XRAIN with its spacial high resolution. 3) There are various storage function (SF) models such as Kimura, Prasad, Hoshi, and urban storage function (USF) models. We aims to identify an effective SF model for an urban watershed in terms of hydrograph reproducibility and from an Akaike information criterion (AIC) perspective. The results revealed that hydrograph reproducibility of USF is the highest among the SF models. The USF model received the lowest AIC score during most of the events, which indicates that it is the most parsimonious model compared to the other SF models.

【Department 】：Department of Civil and Environmental Engineering, Faculty of Environmental Engineering 【Name 】：Jun MURAKOSHI 【Position 】：Professor 【Research Topic 】：Bridge Engineering, Steel Bridge Design, Remaining Load-carrying Capacity Evaluation and Fatigue Evaluation of Steel Highway Bridge, Repair and Strengthening
【Outline of research achievement 】 1) Research on performance evaluation of SFRC overlays as a measure to improve durability of existing orthotropic steel decks Murakoshi,J. With rapid increase of truck weight and traffic volume in Japan, various types of fatigue cracks have recently been observed in existing orthotropic steel decks (OSDs) under severe traffic condition. As an effective retrofit measure to prevent those cracks, steel fiber reinforced concrete (SFRC) overlays have been increasingly used for damaged OSDs. On the other hand, there are not sufficient data to confirm its durability. It is important to investigate the durability performance under the effect of repeated wheel load and environmental action. The purpose of the research is to clarify durability of adhesively bonded joints between SFRC and deck plate, and to propose testing procedures for evaluating the durability. In this fiscal year, in order to clarify deterioration tendency of tensile strength/shear strength of the adhesively bonded joints, core extraction tests and shear tests of the joints were conducted using small-size test specimens with two types of adhesives.
2) Research on evaluation of fatigue durability of existing steel I-girder highway bridges Murakoshi,J. and Kishi,Y. Serious fatigue damage which may lead to fracture of main girder have been observed on steel I-girder highway bridges under severe traffic condition in 2006. To assure structural safety of huge number of aging steel bridges, it is important to manage those bridges by efficiently considering information about fatigue vulnerability in addition to periodic inspection. The purpose of this research is to assess fatigue vulnerability of existing steel I-girder bridges constructed in 1960’s and 1970’s, when fatigue design were not adopted. In this fiscal year, a simplified method to estimate fatigue design live load stress by using load distribution factor (LDF) was investigated. Regression analyses were conducted using structural parameters and fatigue live load stresses obtained by frame analyses in order to find an accurate LDF equation to calculate fatigue live load stress. And simplified GDF equations for interior and exterior girders were proposed.
3) Research on evaluation method of remaining load carrying capacity for existing structural members in steel and composite structures Murakoshi,J., Nogami, K. and Kishi,Y. In Japan, majority of highway bridges was constructed during the high economic growth period and the number of bridges over 50 years is increasing drastically. With increase of aging bridges, it is highly probable that deteriorated bridges increase rapidly since many of them are exposed to heavy traffic condition and severe natural environment. Corrosion is a major damage for steel bridges, especially at girder end, and sectional loss of structural members can result in decrease of the load carrying capacity. With regards to steel truss bridges, severe corrosion with sectional loss around gusset connections often have possibility to lead to a crucial problem such as bridge collapses. However, in the both cases, since corrosion appears in various forms, for the present, effective techniques to evaluate the ultimate strength of the whole bridge with corroded members are under development. This research focuses on proposing a practical approach for evaluating remaining capacity of bridge systems with severe corroded bridge members. In this fiscal year, finite element analyses of a girder end specimen cut out from a severely corroded highway bridge were conducted to investigate the effect of the section loss on the remaining capacity and to develop appropriate analytical model.
4) Research on fatigue durability improvement of welded joints of orthotropic steel deck bridges Murakoshi, J. With rapid increase of vehicle weight and traffic volume in Japan, various types of fatigue cracks have recently been observed in existing Orthotropic steel deck (OSD) bridges under severe traffic condition, resulting from the complicated welded details combined with local stresses that can be difficult to quantify in the design. Regarding the design of OSDs, fatigue-resistant details are specified in the Fatigue Design Guideline of Steel Highway Bridges issued in 2012. However, in some structural details, further research is considered necessary to standardize appropriate structural details with more fatigue durability for newly constructed OSD bridges. In this research, focusing on top details of vertical stiffener of OSD bridges, fatigue improvement details are experimentally/analytically compared with the current details from the viewpoint of fatigue resistance. In this fiscal year, fatigue tests for current details and improvement details were conducted and their crack behaviors and fatigue strength by various reference stress were investigated.

The achievement of this year is as follows, (1) In order to determine the effect of forest management on the prevention of sedimentation and eutrophication in the Ogouchi reservoir, 60 years data of rainfall and discharge were analyzed, and changes of runoff process and water content capacity of soil were determined every decade. It was suggested that change of runoff was scarcely found but water content increased slightly during 60 years. (2) Saltwater intrusion and feature of river bed sediment were measured continuously from spring to autumn, and process of deposition and erosion was analyzed. Bed sediment was composed of sand and gravel after rainfall exceeding 15 mm/h and it was composed of organic matter when rainfall was less than 15 mm/h. Deposited organic matter surfaced 4-5 days after a light rain. (3) Particle motion model was incorporated into three dimensional hydrodynamic model for estuary. The model was composed of phytoplankton movement which float with light during daytime and settle down during night, and fish egg with density. (4) Field survey on saltwater intrusion and estuarine turbidity maximum in the Tanintharyi river estuary, Myanmar was carried out. Bed topography was surveyed and bed sediment was collected, and vertical profiles of water quality parameter such as salinity, temperature, turbidity, chlorophyll and DO were measured by using CTD.

【Department 】：Department of Civil and Environmental Engineering, Faculty of Urban Environmental Sciences 【Name 】：Hideo AMAGUCHI 【Position 】：Assistant Professor 【Research Topic 】：Hydrology, River Engineering 【Outline of research achievement 】 Impervious areas such as buildings and roads, and permeable areas such as parks and green spaces are distributed complicatedly in urban watershed. In order to accurately analyze flood runoff processes and hydrological processes in such river basins, it is necessary to prepare land use data that accurately expresses ground features such as buildings, roads, parks that is constituting cities, it is necessary to construct a distributed flood runoff analysis model and hydrological model as input data. Model set up for urban landscape GIS requires a lot of time and effort because it requires manual processing. In this study, among a method for generating feature geometry elements in a town block, a block division method focusing on the shape of the building was examined and it was applied to a real city block. As a result, the block can be divided while considering individual buildings with a relatively simple algorithm, and it is thought that using this method makes it easy to generate model data for individual building flood analysis by the TSR model. It is desired to reduce the labor and shorten the time which was regarded as a problem in manual work by this method.

【Department 】：Department of Civil and Environmental Engineering, Faculty of Urban Environmental Sciences 【Name 】：Yusuke KISHI 【Position 】：Assistant Professor 【Research Topic 】：Structural Engineering, Disaster Mitigation, Seismic Engineering 【Outline of research achievement 】 1）Research on Coupled Buckling Strength Evaluation for Compression Member of Steel Bridges. SBHS500 is new material described in Specifications for Highway Bridges (JRA) in 2017. Few examples are this steel for bridges, and it is not revealed the variation of performance. In order to investigate the performance of evaluate the coupled buckling strength of box type cross-section members, compression loading test were carried out. This specimen loaded once, however the compression strength of the specimen was higher than the capacity of loading machine. Therefore, the loading test was carried out under other loading condition. 2) Numerical Verification for Constitutive Law’s Parameter of Cyclic behavior of Steel Materials. In order to estimate strain’s value of steel members during earthquake motion, cyclic loading tests were carried out about SM570 material. This strain value is one of the important factor for seismic design. Therefore, parameter fitting for commercial software were verified based on the experimental results described in above. 3) Numerical Simulations of Crowd Evacuation during Volcanic Disaster Simple numerical simulations were carried out, in order to verify the crowd evacuation on pacific islands area of Tokyo Prefecture.
