Wind Hazards Reduction Program
The 1990's mark the International Decade for Natural Disaster Reduction. In this context, the Wind Effects Committee of the Structural Division strongly endorses the establishment of a...
Diagnosing Lateral Strength of Existing Concrete or Masonry Buildings
A research prospectus is presented for improving present methods of structural evaluation for concrete and masonry buildings. Specifically, the proposed research plan is limited to strength...
Development of Computer-Based Models of Standards and Attendant Knowledge-Base and Procedural Systems
Existing and new technology can be used to develop a new generation of standards that would allow designers to use complex standards efficiently, help standard-writing bodies to detect...
Investigation of Diaphragm Walls to Improve Performance, Design, and Construction
As a result of the need for tunnels, underground highways and parking structures, cofferdams, facilities related to the improvement of the environment, etc., there has been a significant...
Bridge Management Research Needs
The present article deals with some aspects of bridge management of particular interest to bridge engineers and to bridge users at the moment. It addresses questions such as life-cycle...
Seismic Strengthening for Structures in Regions of Low Seismicity
Most existing structures were not designed to today's seismic codes and standards, and in fact in low seismicity regions codes did not require seismic design until recently....
Seismic Assessment and Renovation Study for Highway Bridges
This paper is concerned with hazards mitigation on highway bridges due to earthquake ground motions. Damage to transportation systems may occur if the acting faults of May-Shan and Tsu-Kou...
Concrete Arch Bridges for Supporting Steel Conduits of Mingtan Pumped Storage Project
For the Mingtan Pumped Storage Project of an installed capacity of 1600 MW, two parallel waterways have been constructed for conveying flows between the upper reservoir and the lower reservoir...
Design of the Main Bridge of the Huachiang Bridge
The Huachiang Bridge will be reconstructed by erecting the deck structure in two steps to avoid reducing or interfering with the bridge's traffic flow. Both the analysis and the detailed...
Developing a New Construction Policy for Bridge Management
The SHRP Program and other rehabilitation strategies are based on extending the life of concrete bridge elements. In the Bridge Inventory are a number of bridges that must be reconstructed....
Proof Loads in LRFD Format for Bridge Evaluation
Proof load testing is considered as a reliable approach to evaluation of an existing structure's load-carrying capacity. It can be effectively used for highway bridge evaluation, to either...
Development of Bridge Load Model for LRFD Code
The load models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck...
Bridge Engineering and Life Cycle Cost
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires that all Federal Aid projects must 'consider...the use of life-cycle costs in the design and engineering of...
Correction Factor Method for Building Analysis Under Sequential Dead Loads
The effect of the sequential application of dead load due to the sequential nature of construction is an important factor to be considered in the multistory frame analysis. One of the...
Wind-Induced Vibrations of Tall Buildings Using Tuned Mass Damper
A Lagrange formulation is applied to tall buildings using tuned mass damper. The resulting equations of motion are analyzed using a frequency window method. The method reduces the computational...
Dynamic Inelastic Analysis of Tall Buildings
Members with undesirably early formed plastic hinges as well as excessive conservatism introduced in the preliminary design of tall buildings can be identified by the behavior state study...
Optimal Design of Building Structures Using the Predetermined Sections
A practical optimization algorithm for the member design of building structure is presented in this paper. The emphasis is particularly concentrated on the practical applicability of the...
Reliability-Based Design of Transmission Towers Under Wind and Ice Loadings
This study suggests a practical but rational approach for the development of reliability-based LRFD criteria for transmission towers under wind and ice loadings in Korea. Based on available...
Floor Response Spectra Analysis Including Correlations of Multiple Support Motions
This paper deals with the response spectrum analysis method of the secondary structures including the correlation effects between nonuniform support excitations. Based on the random vibration...
A Reduced Order Model for the Seismic Analysis of Building-Soil Systems
A finite element based, reduced order, numerical model has been developed for the nonlinear analysis of building-soil systems. The reduced order system model employs an equivalent continuum...
