This paper is concerned with the inelastic behavior of axially loaded concrete-filled thin-walled steel tubular columns subjected to local buckling. A nonlinear fiber element analysis program accounting for local buckling effects is developed for predicting the ultimate strength and ductility of concrete-filled thin-walled steel tubular columns. The effects of local buckling are taken into cons...

This paper reviews selected recent innovations that expand the range of applicability of a number of new and emerging structural steel systems that can provide effective seismic performance. Focus is on recent developments on: (a) Steel Plate Shear Walls having light gauge infill plates; (b) Perforated Steel Plate Shear Walls; (c) Buckling Restrained Braced frames designed to meet Structural Fu...

To measure the cleanability of stainless steel surfaces under standardized conditions, a test stand was set up. Three stainless steel plates (size 200 x 100 mm) can be fixed to the test stand and sprayed with a water jet from a low-pressure nozzle for a period of several minutes. The plates were previously soiled with a starch or protein film with a pre-defined layer thickness and dried for sev...

design of bridge deck with long-term strength, durability and permanence is a significant interest for engineers. one applicable solution to this challenge could be via using hybrid system consisting of conventional materials such as concrete and steel with frp plates which is also known as composite deck. since these deck are relatively new so their performance is not completely known. the pre...

In this research in-plane shear Behavior of composite steel-concrete shear walls was investigated considering the Effects of steel plates thickness, spaces between shear studs, shape and type of shear studs and existing of minimum reinforcement in wall section. Several finite element models were analyzed and Numerical results of two models were taken under verification with existent experimenta...

Experimental and numerical investigations were conducted to assess the effectiveness of polymeric coatings to enhance the blast protection of steel structures. During the experiments test plates were allowed to deform under close-in blast loading and the final deformations of coated and uncoated plates were compared. The coatings were found to reduce the deformation of the plates when applied t...

The paper reports on the noise and vibration control of a 451 m long steel railway bridge. The vibration and noise generation mechanisms were investigated first. Vibration of the rail fixture, sleeper, horizontal and main girders and the steel walking plates were measured, together with noise measurements in a number of measuring points both in the close vicinity of the bridge and at larger dis...

Plates of austenitic stainless steel are often used in orthopedic surgery for fixing ends of the broken bones and for repairing fractures. The paper analyzes a premature breakage of six plates for fixing broken bones with different patients during their recovery. Each plate's breakage can induce serious aftermaths such as a new surgery, unexpected undesired complications and a prolonged healing...
