Interaction of Cable Roofs with Support Structure
Tensioned structures are becoming increasingly popular for covering large column free areas on account of efficient utilization of construction material, speedy construction and economy....

Finite Beams on Elastic Foundation with Restraints
A solution is presented of the differential equation of finite beams with elastic restraints, resting on a Winkler foundation in terms of the initial conditions at one end of the beam....

Dynamic Characteristics of Frame-Wall Systems
The first three natural frequencies and the corresponding mode shapes for fixed-base frame-wall systems are presented. The system is modelled as a continuum of uniform properties incorporating...

Beam Idealization
For any given bemm with varying cross-section and material properties, it is easy to evaluate a number of parameters Qi and Di,...

Ultimate Strength of Arches with Bracing Systems
The ultimate load carrying capacity of bridge arches is investigated for the case where they fail by inelastic lateral instability associated with the flexural-torsional deformation of...

Hysteresis Models for Reinforced Concrete
Nonlinear dynamic response of a simple reinforced concrete specimen is studied using five different hysteresis models: the Takeda, elasto-plastic, bilinear, Clough, and the Q-hyst model....

Seismic Hazard Analysis of Lifelines
Methods for assessing the seismic safety of a lifeline system are developed; with part of the study being devoted to the development of a relation between the earthquake intensity and...

Optimum Design of Reinforced Concrete Water Tanks
The conventional method of designing water tanks is irrational and leads to relatively thick walls with a substantial amount of reinforcement. Application of the limit state method results...

Buckling of Pretwisted Columns
The effect of pretwist on the buckling load of column is presanted. A finite element formulation is developed for the stability analysis of pretwisted columns. Numerical examples are used...

Loads due to Drifted Snow
Roof failures due to snow loads are often the result of heavy drifts rather than uniform snow loads. Codes and standards such as Standard A58.1 of the American National Standards Institute...

Simulation of a Buried Power Transmission System
This paper examines the simulation of the motion of three power cables (three-dimensional nonlinear beams) which are constrained to move within a pipe under thermal loads. The cables are...

Tensegric Shell Behavior
Tensegric shells are composed of cable or membrane envelopes prestressed by lengthening properly arranged bars connected at both of their ends to the envelope and not touching each other....

Rigid-Body Response of Base-Isolated Structures
The problem of control of rigid body response of structural systems such as nuclear islands, which are mounted on a gird of bearings with three dimensional damping and stiffness properties,...

Natural Oscillations of Suspension Bridges
Natural modes and frequencies of a simple span suspension bridge with straight backstays are investigated, theoretically and experimentally. Fourier series representations of cable displacements...
