Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web which provides the girder’s shear capacity. Failure of the web occurs by steel yielding, web buckling or interactively between them. Lateral torsion and local flange buckling of corrugated web gird...

A class of planar, pin-jointed truss structures based on the ancient Kagome basket weave pattern with exceptional characteristics for actuation has been identified. Its in-plane stiffness is isotropic and has optimal weight among planar trusses for specified stiffness or strength. The version with welded joints resists plastic yielding and buckling, while storing minimal energy upon truss bendi...

This study investigates the buckling behavior of short cylindrical shells with hemi-spherical heads subjected to hydrostatic pressure. It is assumed that the length of the cylindrical part is smaller than or equal to its diameter while its material may be dif-ferent from that of hemispherical heads. Finite element analysis was used to seek out the effect of geometric parameters such as thicknes...

The use of composite materials for strengthening the ailing infrastructure has steadily gained acceptance and market share. Employing composite materials in strengthening of steel structures is the subject of this study. There are several challenges that face strengthening steel structures using composite materials. The superior mechanical properties of steel result in a reduction in the effici...

iii Summary Computations were performed to determine the eect of an overall bow-type initial imperfection on the reliability of structural panels under combined compression and shear loadings. A panel's reliability is the probability that it will perform its intended function|in this case, carry a given load without buckling or exceeding in-plane strain allowables. For a panel loaded in compres...

Buckling analysis of rectangular plates subjected to various in-plane compressive loads using Kirchhoff plate theory is presented. The method of discrete singular convolution has adopted. Linearly varying, uniform and non-uniform distributed load conditions are considered on two-opposite edges for buckling. The results are obtained for different types of boundary conditions and aspect ratios. C...

Understanding how a cutout influences the load bearing capacity and buckling behavior of cylindrical shells is fundamental in the design of structural components used in automobiles, aircrafts, and marine structures. In this article, simulation and analysis of steel cylindrical shells with various lengths, include quasi elliptical cutout, subjected to axial compression were systematically carri...

The large difference between in-plane and out-of-plane mechanical properties limits the application of traditional composite honeycombs in submersibles. In this work, carbon fiber tube reinforced polymer (CTPC) which have lightweight characteristic high hydrostatic strength is designed manufactured. combination epoxy resin inhibits buckling failure improves bearing capacity tube. Resin binds tu...

The mechanical properties of composite membranes obtained by self-assembly of actin filaments with giant fluid vesicles are studied by micromanipulation with optical tweezers. These complexes exhibit typical mechanical features of a solid shell, including a finite in-plane shear elastic modulus ( approximately 10(-6) N/m). A buckling instability is observed when a localized force of the order o...
