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...

Development of an Improved Rapid Seismic Analysis Procedure
New developments in computer capabilities and lessons learned from recent earthquakes have facilitated improvement of the Rapid Seismic Analysis Procedure (RSAP) currently specified in...

New Views for Modeling Dynamic Response of URM Buildings
Various computational models are used to depict seismic response of an unreinforced masonry building that was subjected to the 1989 Loma Prieta Earthquake. The worthiness of various analytical...

Finite Element Analysis of a Highway Bridge Hinge
A highway bridge hinge is a very important element in bridge design. It releases thermal stresses that may be developed in the superstructure or the substructure of a bridge. A common...

An Innovative Connection Detail for High-Rise Buildings
Composite columns consisting of hollow steel tubes filled with high strength concrete have been used in high rise building construction in the USA and Far East Asian countries. The focus...

Seismic Design of Steel Beam-to-Box Column Connections
This paper is a study of the ductility requirements of steel beam-to-box column connections using the bolted beam web and welded beam flange details. Since the beam moment at the connection...
