Ali2 1Urban Planning and Policy Department, University of Illinois, Chicago, IL 60607, USA 2School of Architecture, University of Illinois at Urbana-Champaign, Champaign, IL 61820, USA Abstract There is much architectural and engineering literature which discusses the virtues of exterior bracing and diagrid systems in regards to sustainability - two systems which generally reduce building materials, enhance structural performance, and decrease overall construction cost. By surveying past, present as well as possible future towers, this paper examines another attribute of these structural systems - the blend of structural functionality and aesthetics. Given the external nature of these structural systems, diagrids and exterior bracings can visually communicate the inherent structural logic of a building while also serving as a medium for artistic effect.

  • Structural Engineering Education in the Twentyfirst Century
    Seventh LACCEI Latin American and Caribbean Conference for Engineering and Technology (LACCEI’2009) “Energy and Technology for the Americas: Education, Innovation, Technology and Practice” June 2-5, 2009, San Cristóbal, Venezuela. Structural Engineering Education in the Twentyfirst Century D. S. Prakash Rao The University of the West Indies, St. Augustine, Trinidad and Tobago The unceasing quest of the society to enhance the quality and standards of living invariably culminates at the plans for the development of infrastructure. The prosperity of any country can be judged by its structures, be it buildings, bridges or towers. A vibrant economy and poor infrastructure rarely co-exist. A nation invests in the infrastructure not only for day-to-day needs but also for commerce, trade, defence, recreation and future development. Structural engineering is in the forefront of development wherever civilisation flourished. The challenges of structural engineers have increased enormously through centuries particularly in the current century with the dreams of multi-kilometre high towers and long bridges besides of establishing colonies on far off planets. Some of the aspects of structural engineering, its education and future trends are discussed in this brief article. Keywords: computer applications, development, education, infrastructure, structural engineering 1. INTRODUCTION The developments in infrastructure parallel the fiscal growth of a country, and reflect the standards of living as well as the vision and courage of engineers. Recent strides in globalisation and liberalisation led to extensive development of infrastructure all over the world. In general, infrastructure includes a wide range of systems such as roads, buildings, bridges, flyovers, communications, transportation, airports, harbours, storage, water supply, services and industry.

Abstract A construction megaproject is defined in literature as a construction project, or aggregate of such projects, characterized by magnified cost, extreme complexity, increased risk, lofty ideals, and high visibility, in a combination that represents a significant challenge to the stakeholders, a significant impact to the community, and pushes the limits of construction experience. Risk assessment in megaproject is the most difficult component in the risk management process. Although it has high relevance to the success of megaprojects, risk management remains one of the least developed research issues. Megaprojects are executed in a dynamic environment and identified risks are to be prioritised based on their impact on project objectives of time cost and quality before they can be modelled .The present paper focuses on prioritising the technical risks associated with the construction of phase 1of Bangalore Metro Rail Project to assess its impact on the project objectives that helps in the decision support system of the project.

With its international attendance and the large range of themes and topics dealt with, the Second International Congress of Construction History organized in Cambridge in spring 2006 was a good proof of it1. Some twenty years ago, a similar enterprise would have been certainly more modest in scope and ambition. This spectacular success provides a good opportunity to question construction history, to envisage in particular the type of relation it has or should have with other domains of historical research. In this paper, I would like to examine in particular its position vis-à-vis history of technology on the one hand, cultural history on the other. While its relation to history of technology may seem simple at first, a closer look reveals a series of complex problems. For construction history represents both an integral part of history of technology and a very special field with strong idiosyncrasies.

  • Vibration Control of Tall Buildings Using Mega Subconfiguration
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Columbia University Academic Commons VIBRATION CONTROL OF TALL BUILDINGS USING MEGA SUBCONFIGURATION By Maria Q. Feng,t Associate Member, ASCE, and Akira Mita,2 Member, ASCE ABSTRACT: An innovative vibration-control system is proposed to reduce the dynamic response of tall build­ ings to wind and seismic loads. This system takes advantage of the so-called megasubstructure configuration, which is especially popular in tall buildings. Substructures contained in the megastructure serve as energy absorbers so that no additional mass is required for the intended vibration control as seen in the conventional mass damper systems. The proposed system naturally resolves the difficulties in augmenting damping capacities of tall buildings associated with the high rigidity and deformation in the dominant bending mode. Dynamic characteristics of the proposed control system including the frequency response and the energy flow are investigated. Optimal values of structural parameters such as the damping ratio and stiffness of the substructure are determined. The feasibility and effectiveness of this unique control system in improving human comfort and protecting structures under both wind and earthquake loads are demonstrated through analytical and numerical analysis. INTRODUCTION number of damping devices needed would be extraordinarily large and, thus, its use would be economically impractical. Traditionally, architects and engineers have been inter­ The tuned mass damper system has been applied to many ested in constructing structurally sound, functionally efficient, actual buildings in which an additional mass is attached to a and esthetically elegant high-rise buildings.
