Iot Safety Belt Alarm System INDUSTRIALISATION IoT Safety Belt Alarm System Modular Integrated Construction (MiC) The LSCM R&D Centre has developed a real-time sensing system to monitor the deployment of safety belts at work site. The system will detect any dangerous situations, such as the absence of the lifeline, the irregular positioning of the lock, or the Modular Integrated Construction (MiC) offers an alternative to convention construction by improper engagement status of the hook. It will notify the site workers in real time to remind them to properly engage their adopting the concept of “factory assembly followed by on-site installation”and the mode of safety devices. manufacturing, labour intensive processes can be accomplished in off-site prefabrication yard with a view to improving the productivity, safety and long-term cost effectiveness. MiC offers a free-standing module solution consisting of steel and fire-resistance structural, architectural Cloud-based Quality Management System and MEP components (complete with finishes for walls, floors and ceilings). Cloud-based Quality Management System such as SnagR can help collect, report, manage and analyse defects on site and identify potential issues for construction projects. Through the Voided biaxial slab mobile device and web-based software, SnagR help saves time and money spent in the quality and field management. The field data assists construction professionals to make better MatrixDeck System is a type of lightweight wide slab floors with integrated lattice girders and decisions and modify management process from time to time. lower reinforcement. Airboxes are positioned on the slabs in a fixed pattern that allows greater column span and minimises the usage of concrete and steel reinforcement. Real-time temperature and maturity monitoring of concrete Wireless sensor networks have many potential applications in construction management Rubberised paving blocks such as monitoring the temperature and maturity of concrete. Strength data are collected in real-time without the need to do destructive tests. Up to 50% direct test cost can be saved Waste tyres are creating a huge burden on landfills in Hong Kong with the increasing number for determination of in-place strength of concrete done by on-site people. of vehicles. Rubber mats and stamped rubber are currently the only recycling products derived from waste tyres. With the use of nanomaterials and surface treatment, rubberised paving blocks are now made possible by incorporating comparatively higher content of waste tyre rubber. Rubberised paving blocks deliver optimised compressive strength which makes them Photogrammetry by UAV (Unmanned Aerial Vehicle) ideal for footpath and cycle path paving application. Photogrammetry by UAV (Unmanned Aerial Vehicle) is more productive and takes less time in site inspection and land surveying compared with traditional methods. Data collected can be INFORMATISATION easily shared with modelling platforms such as BIM to enable easy and timely visualisation of the Construction Workers Registration System (CWRS) site and its details by construction professionals. CWRS is developed by the CIC to implement a registration system for construction workers as required by the Construction Workers Registration Ordinance (Cap.583). It enables the Building Information Modelling (BIM) collection of accurate attendance records and their analysis for overall manpower planning. A new card reading device (“CIC Device”) has been developed to simplify the registration process 3D Virtual Reality (VR) Experience for Xiqu Centre for construction workers and support new CWR Card which stores multiple qualifications and card tapping records. Virtual reality and augmented reality, with the help of Building Information Modelling (BIM), have significant potential to deliver customer focused products. For example, rather than looking at pictures of what a scheme may look like, we can experience it in a simulated 3D environment, like the West Kowloon Cultural District Xiqu Centre. This enables them to IoT (Internet of Things) Safety Helmet experience the structure as if it had already been built and understand what the structure will look like before it is finished, so that they can give more detailed and accurate feedback on the proposals before construction commences. IoT (Internet of Things) Safety Helmet is a smart device that can monitor the health and the safety of construction workers. It has various sensors to resist collision and monitor the body temperature, heart rate and movement of construction practitioners. It can be easily adapted to INTELLIGENTISATION existing safety helmets and can be implemented in every construction site. Data collected is stored and analysed by a cloud-based management portal.

    © 2019 JETIR June 2019, Volume 6, Issue 6 www.jetir.org (ISSN-2349-5162) SEISMIC ANALYSIS OF KINEMATIC BEARINGS USING VOIDED BIAXIAL SLAB Mirajj Ketan Thaker , Dilesh Solanki, Dhruval Suriya ,Venkatesh Rajput Student, Student , Student , Assistant Professor Civil engineering Department, Universal College of Engineering, Mumbai, India. Shreya Gaikwad, Student, St. Francis Institute of Technology, Mumbai , India. Abstract The basic intention of seismic protection systems is to decouple the building structure from the damaging components of the earthquake input motion, that is, to prevent the superstructure of the building from absorbing the earthquake energy. This paper reviews the experimental study and model simulation of kinematic bearings with use of voided biaxial slab system (uboot technology). Shaking table test was done. from moderate to severe vibrations and effects like gyro, acceleration, drift, maximum displacement was derived. The aim is to build such type of structure which provides maximum stability and minimum damage to building components during seismic action, also to make structure economical and environmentally sustainable in seismic zones Keywords- seismic waves, polypropylene, rubber Bearings, voided slab. 1. INTRODUCTION Earthquake is amongst the catastrophic natural calamities where an abrupt movement or tremor is initiated under earth’s causing major damage to mankind. Although a great deal of research has been carried out regarding seismic isolation, there is a lack of proper research on its behavior and implementing technique in low to medium seismic region. From past earthquakes, it is demonstrated that a significant number of structure are absolutely/somewhat harmed because of earthquake and now-a-days it has turned out to be important to decide seismic reactions over such structures.

Singh Copyright © 2015 Shujin Li et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. This paper proposes a novel tuned mass damper (TMD) embedded in hollow slabs of civil structures. The hollow slabs inthis context, also referred to as “voided biaxial reinforced concrete slabs,” feature a large interior space of prefabricated voided modules that are necessary in the construction of this special structural system. In this regard, a tuned rolling mass damper system (“TRoMaDaS”) is newly proposed, in combination with hollow slabs, to act as an ensemble passive damping device mitigating structural responses. The main advantage of this TMD configuration lies in its capacity to maintain architectural integrity. To further investigate the potential application of the proposed TRoMaDaS in seismic response mitigation, theoretical and numerical studies, including deterministic and stochastic analyses, were performed. They were achieved by deterministic dynamic modeling using Lagrange’s equation and the statistical linearization method.

  • Implementering Av VBS System I Sverige
    Examensarbete 15 högskolepoäng C-nivå Implementering av VBS system i Sverige Asmaa Tarek och Zhir Farhad Byggingenjörsprogrammet 180 högskolepoäng Örebro vårterminen 2020 Examinator: Mats Persson Implementation of VBS system in Sweden ​ Örebro universitet Örebro University Institutionen för naturvetenskap och teknik School of Science and Technology 701 82 Örebro SE-701 82 Örebro, Sweden FÖRORD VBS (voided biaxial slab) är en teknik som går ut på att minimera betongen i plattorna och ersätta med ihåliga plastbollar istället. På så sätt reduceras betongplattans vikt, vilket medför fördelar till konstruktionen. Det tillämpas på flera håll i världen och i denna rapport görs en undersökning om VBS kan implementeras i Sverige också. Fördelar och nackdelar av VBS systemet lyfts fram och jämförs med konventionell massiv betongplatta. Detta examensarbete är utförd av Asmaa Tarek och Zhir Farhad som är studenter vid Örebro universitet, högskoleingenjörsprogrammet i byggteknik. 1 2 SAMMANFATTNING Betong är idag ett av de material som vi använder mest i byggbranschen och det har sina följder. Mer än 50 % av energiutsläppen från byggplatsen kommer från cementtillverkningen. Voided biaxial slab eller VBS är en revolutionerande teknik där man gjuter in plastbollar i betongen tillsammans med armeringen. Arbetstiden samt torktiden kortas ned samtidigt som vi bevarar hållfastheten och dess funktionalitet. I den här rapporten kommer vi titta närmare på VBS teknik och jämföra det med konventionell betongplatta och se om tekniken är lämplig för att implementeras i Sverige. Vi har använt oss av en kvalitativ metod i form av källanalys från internet och tryckta källor. Även en komparativ metod i de fallen vi har hittat information från mer än en källa.
