The mechanism of blast damage to steel-clad concrete-filled steel tube (SCCFST) arched protective doors is studied using the dynamic response characteristics such loads under action shock wave loads, and ultimate load-bearing capacity formula derived based on “plastic hinge” mode limit analysis, which explores effect wave. design parameters each component door subjected waves discussed. Results...

Steel-tube grouting technology has been widely applied in the slope control engineering. While anti-sliding performances of different connection modes grouted steel tubes still needs further investigation. In this paper, a large-scale model test was used to study influence three types pile connections, namely whole without connection, with reinforcement welded and casing on performance multi-st...

A new research program has begun at UNLV in accelerator transmutation of waste. Lead Bismuth Eutectic (LBE) has been proposed for use in programs for accelerator transmutation of waste. The LBE acts both as a coolant and as a sputtering target. We have recently initiated a program to investigate the corrosion of steels by LBE. Corrosion products and chemical reactions will be identified using U...

This paper presents the results of reliability analyses load-carrying capacity circular concrete filled steel tubes (CFST) using different codes. Four parameters that govern CFST were considered as variables. These variables include yield strength steel, concrete, diameter CFST, and thickness tube. The Monte Carlo technique was used for simulation. Simulations conducted, obtained capacities ana...

In this paper, the laser bending process of a circular tube made of mild steel has been investigated experimentally. For this purpose, the effects of the irradiating length and the number of irradiating passes on the main bending angle of a laser bent tube are studied. In addition, the main defects of the laser tube bending process such as lateral bending angle, ovality and thickness variation ...

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...

Nowadays, due to the escalation in construction of high-rise structures, the need for selecting a proper resistant structural system against earthquake and wind has increased significantly. These systems should show an optimized use of materials and should be presented as a hard and efficient structure. A good example of a high efficient system in high-rise buildings can be indicated is, the tu...

Introduction: To present and assess a newly designed autoclavable, reusable tube shield for an endotracheal tube (ETT) during laser laryngeal surgery.   Materials and Methods: This study included patients scheduled for endolaryngeal laser surgery. A carbonated stainless-steel hemisphere shield (~1.5×0.6 mm) connected to a silk thread passing through a hole in its middle near upper edge was ...
