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...
Investigation of Full-Scale Performance of Structures?Research Potentials
It is well known that actual, or true, behavior of completed structures does not necessarily conform to often simplified analysis predictions. This may be due to any of several reasons...
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...
Behavior of Horizontally Curved Steel Highway Bridges
Horizontally curved highway bridges represent up to 25 percent of the market for new steel-bridge construction each year. However, unanswered questions remain concerning the fundamental...
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...
Joint Design in Composite Columns/Steel Beam Structures
The use of a composite building system, utilizing a composite exterior column and a concrete spandrel beam system, proposed by Dr. Fazlur Khan in 1967, is recalled. In the last 25 years,...
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....
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...
MRT Cable Supported Roof
A cable supported roof structure for Chientan station (R18A) at Taipei Mass Rail Transit system's Tan-Sui line are under construction. Unique wind and cross sectional dynamic effect has...
Lateral Bracing of Plate Girders Using Deck Forms
The initial results of a study of the ability of stay-in-place steel deck forms to stabilize bridge girders during construction is presented. The analytical and experimental results to...
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...
Bonded Polyester Concrete Overlays Used in California
Bonded polyester concrete overlays have been very successful in California in restoring and preserving bridge decks from damage by road salts. The polyester concrete system has been employed...
Nondestructive Inspection of Steel Bridge Members
Assessment of the conditions of an aging population of bridges in order to determine the proper maintenance or retrofit operation is a challenge of great importance to bridge engineers...
Nondestructive Evaluation of Timber
Nondestructive evaluation of materials, the science of identifying the physical and mechanical properties of materials without altering their end-use capabilities, is valuable in defining...
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...
Reliability of Highway Bridge Piers
Structural safety of reinforced concrete bridge piers supporting highway traffic is studied. Reliability indices for flexure, shear, and combined flexure and axial load limit states at...
Experimental Testing of Laterally Loaded Large Scale Bridge Abutments
The challenges to a bridge analyst in defining abutment boundary conditions and the current state of the practice are presented. Variables within the abutment system are defined and discussed...
After-Fracture Response of a Two-Girder Steel Bridge
The I-40 bridges over the Rio Grande are due to be razed in mid 1993 due to geometry and traffic safety considerations. The bridges are classified as 'fracture critical' two girder steel...
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...
An Efficient Analysis of Framed-Tube Structures
An efficient model for analysis of framed-tube systems is proposed in this study. The proposed model can represent the interaction between plane frames consisting the tube system. Analysis...
