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...
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,...
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...
Linear and Nonlinear Finite Element Analyses of RC Skewed Slab Bridges with Integral Wall Abutments
The design of rigid-frame skewed slab bridges is complicated by higher shears and moments near the obtuse corner (see Fig.1). While the finite element method can be used to compute these...
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...
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...
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...
Modal Analysis Technique for Bridge Damage Detection
The dynamic responses of a wide-flange steel beam with artificially introduced cracks were studied analytically and experimentally. Frequencies, displacement mode shapes (DMS) and strain...
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...
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...
