thin-walled hollow steel columns, either circular or box shaped, are commonly used as piers in bridges. recent earthquakes, e.g. hyogoken-nanbu or kobe 1995, on the other hand have shown that these columns are vulnerable to damage when subjected to earthquake loading. this paper presents a new innovative thin-walled hollow steel column fabricated of corrugated plates, “thin-walled steel columns...

a comparison between design codes i.e. aci and aisc-lrfd in evaluation of flexural strength of concrete filled steel tubular columns (cfts) is examined. for this purpose an analytical study on the response of cfts under axial-flexural loading is carried using three-dimensional finite elements with elasto-plastic model for concrete with cracking and crushing capability and elastoplastic kinemati...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...

existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. therefore, it must be considered in stress analysis and designing and loading of such structures. in this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...

Metal thin-walled members have been widely used in building industry. Usually they are utilized as purlins, girts or ceiling beams. Due to slenderness of thin-walled cross-sections these structural members are prone to stability problems (e.g. flexural buckling, lateral torsional buckling). If buckling is not constructionally prevented their resistance is limited by buckling strength. In practi...

in this research, softening and ratcheting behaviors of ck20 alloy steel cylindrical shells were studied under displacement-control and force-control cyclic axial loading and the behavior of hysteresis curves of specimens was also investigated. experimental tests were performed by a servo-hydraulic instron 8802 machine. the mechanical properties of specimens were determined according to astm e8...

Abstract This paper presents numerical simulations on the behavior of thin‐walled steel tubular bridge piers box sections under cyclic lateral loading in presence constant axial compression loads, using three‐dimensional finite element analysis adopted commercial computer software ABAQUS. The and experimental results are compared to show how material models, such as elastic perfectly plastic (E...
