This paper presents the result of a parametric study on the seismic behavior of minimum weight-designed structures with and without added viscoelastic dampers. The structures are first...
Viscoelastic Dampers for Seismic Pounding Mitigation
A hysteretic model for viscoelastic (VE) damper is explained. The model accurately accounts for the effects of excitation frequency as well as temperature of the damper. Benefit of using...
Recent Developments in Seismic Isolation Technology
Large experimental research projects for isolators for both civil structures and nuclear reactor applications have been conducted at the Earthquake Engineering Research Center (EERC) over...
Mitigation of Wind-Created Risks During Construction
Wind damage to structures during construction has been found to be significant and often catastrophic. Structural failures are often the result of wind loads that are far less than the...
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...
Axial Capacity of Concrete Infilled Steel Box Column with Biaxial Bending
The objective of this study was to investigate the feasibility of using the Bresler reciprocal load method to calculate the axial capacity of a concrete infilled steel box column subjected...
Design of Stay Cables
Cable stayed structures, consisting of slender superstructure, stay cables and pylons are optimal systems for long span structures with regard to design an economy. The important function...
Response of Concrete Filled Grid Decks Under Static Loads
This paper briefly discusses the bending strength and stiffness of concrete filled grid decks that are subjected to static loads. The influence of design parameters (traffic flow direction,...
Inelastic Bridge Rating Procedures for Steel-Girder Bridges
Current bridge rating procedures for steel beam and girder bridges ignore the ability of the structure to redistribute forces both longitudinally and laterally. When rating steel bridges...
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....
