Methods for Improving the Seismic Response of Concentrically Braced Steel Frames
This paper briefly reviews various factors contributing to the poor performance occasionally observed in concentrically braced steel frame structures during recent earthquakes. Several...

Unusual Shaped Highrise Buildings in Seismic Zone
The structural concepts, seismic analysis and design of five recent highrise structures are presented in this paper. The paper deals with the problem of multistory buildings having 'structural...

Serviceability Limit States in Load Space
Deflection and elastic limit state curves are drawn in load space using a nonlinear structural analysis program. Use of load space simplifies computation of point estimates of serviceability...

Application of Normal Integration Formulas to Bridge Reliability Analysis
Structural reliability analysis often involves extensive integration of complex multivariable functions. Special techniques can be used to reduce this numerical effort. This paper deals...

Probabilistic Models of Fatigue Crack Growth
The reliability of a structure against metal fatigue is a problem that has been of concern to engineers for a very long time. This problem was one of the first to be approached probabilistically,...

Applications of Fiber Bundle Model to Structural Engineering
The bundle failure time has been studied extensively for both deterministic and random loads. The objective of this paper is to apply results in these studies to the dynamic analysis of...

Seismic Response Component in the Risk Assessment of Dams
The risk analysis model for dams that is discussed in this paper considers the probability of an initiating event and the following conditional probabilities of the system response, the...

Seismic Decision Analysis for Jackson Lake Dam
This paper presents a framework for decision analysis that can be applied to seismic dam safety problems. The framework provides a means for displaying uncertainties in a manner that allows...

A Simple Microcomputer Finite Strip Analysis
The development of a finite strip analysis of thin-walled section buckling behaviour is outlined. The analysis uses plate theory for out of plane deflection behaviour and beam theory for...

Recent Developments of the Finite Strip Method
The finite strip method is approaching a state of maturity as a structural analysis technique, as the well known finite element method has done. Two comprehensive (although somewhat dated)...

Optimum Cut-Outs on Plate Stability
Cut-outs are unavoidable in some of the plate components. To minimize the plate weight, in the meantime, to maintain the critical buckling load as high as possible is one of the major...

Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...

Behaviour of Thin-Walled Channel Sections in Bending
The effects of local buckling on the behaviour and load carrying capacity of thin-walled cold formed steel plain channel sections is examined. The bending is applied in such a way that...

Simplified Steel Compression Member Design
The objective of this paper is to present a simplified method of designing steel columns subjected to axial loads and moments for use in situations where automated design methods are inappropriate....

Maximum Response of Buildings to Multi-Seismic Input
The paper presents a technique of determining the maximum response of a torsionally-translationally coupling structure subjected to three ground translational components. It was found...

Local Buckling and Cyclic Behavior of Tubular Members
The effect of the local buckling is included in the cyclic analysis of tubular members. The cyclic moment-curvature curves are obtained numerically. Three types of closed form expressions...

Cyclic Behavior of Concrete-Filled Tubes
This paper presents the results of tests on hollow and concrete-filled rectangular tubes subjected to cyclic bending and buckling. It is shown that concrete infill greatly improves the...

Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...

Response of Buried Structure Walls to Earth Penetrating Conventional Weapons
A structural analysis method is presented which accurately models the interface condition between a buried structure and the surrounding soil. During the loading phase, continuity of both...

Dynamic Simulation of Foundations on Winkler Subgrade
The objective of this paper is to present a dynamic simulation of foundations on Winkler subgrade. The analysis is based on a direct simulation procedure. The structures have been modeled...
