The ultimate strength of axially loaded jumbo columns with biaxial initial out-of-straightnesses is analyzed by the finite element method. The analysis makes use of the measured residual...
Optimal Location of Active Controllers Subjected to Seismic Excitation
In the application of structural control to seismic structures certain locations are advantageous for placement of the actuators. These locations reduce the structure's response...
A Study of the Precision of Optimum Design Using Suboptimization
As the scale of structures becomes larger and their configuration become more complicated, the design variables and constraint conditions increase, and numerical calculation of the optimum...
Stress Computations for Nearly Incompressible Materials
Computation of stresses by the finite element method (FEM) in the case of nearly incompressible isotropic elastic materials is discussed. It is shown that for moderately high Poisson's...

This paper describes an integrated knowledge system for the assessment of the seismic vulnerability and risk of engineered facilities. The system integrates knowledge from many fields...
High Strength Concrete: Proportioning, Behavior and Applications
Generally, concrete with a cylinder compressive strength higher than 6000 psi (41.4 MPa) is designated as high strength concrete. High strengths are achieved using stronger coarse aggregates,...
Review of Composite Analysis Methods for High Temperature Applications
This paper addresses a number of unique problems encountered in the stress analysis of high temperature composite materials. The materials used as structures subjected to temperatures...
NDE for Performance of Wood Structures
Significant economic losses result annually due to deterioration and failure of structural wood components. A high percentage of these losses result from our current inability to assess...
Effect of High Frequency Response on Fatigue of Offshore Structures
Welded steel specimens have been tested under several loading spectra to determine the effect on fatigue life of high frequency components in the psd of the stress or strain in the joint....
Flexural and Shear Moduli of FRP Beams
The analysis and design of structures of pultruded fiber reinforced plastic (FRP), constant cross-section, commercially produced, beams is discussed in the context of a shear deformation...
Effect of Temperature on the Load-Carrying Capacity of Fiber Glass Reinforced Plastic Beams
This paper describes an experimental investigation into the behavior of two T shaped beams made of fiber glass reinforcement and polyester or vinylester binders. Tests were performed at...
Analytical Model for RC Panels Under Cyclic Load
There are several existing constitutive laws for cracked concrete and steel in RC developed in Okamura laboratory. These models have been developed and verified through reversed uniaxial...
Panel-Sheathed Shear Walls ? Past and Future
In order for a building to resist the lateral forces caused by wind or earthquake, it is necessary that the building include a lateral force resisting system. When the walls are designed...
Study of Partially Prestressed Beams With Unbonded Post-Tensioning
Test on partially prestressed members with bonded Post-Tensioning started recently. Experimental information regarding partially prestressed members having unbonded post-tensioning is...
Shear Strength of P.P.C. Beams
50 beams of partially prestressed concrete were tested and 82 data of the ultimate shear-strength were obtained. Based on these results, this paper studies the effects of the degree of...
Time Dependent Analysis of Partially Prestressed Composite Members
The object of the paper is to develop a computer based procedure for analysis of members made up of precast prestressed concrete sections with cast-in-place topping. The procedure accounts...
Guidelines for Application of FEM to RC Design
In this paper, the main contents of the guidelines for the application of FEM analysis to the design of reinforced concrete structures are presented. The guidelines were published by the...
