In recent years, steel-concrete composite shear walls have been widely used in enormous high-rise buildings. Due to their high strength and ductility, enhanced stiffness, stable cycle characteristics large energy absorption, such can be adopted auxiliary buildings, surrounding the reactor containment structure of nuclear power plants resist lateral forces induced by heavy winds severe earthquak...

In this study, non-linear behavior of diagonally stiffened steel plate shear walls as a seismic resisting system has been investigated, and theoretical formulas for estimating shear strength capacity of the system have been proposed. Several validated analytical finite element models of steel shear walls with various stiffener dimensions are generated to verify and compare the analytical and th...

AIM This prospective study was undertaken to evaluate whether stable patients with haemopericardium could safely be managed with subxiphoid pericardial window (SPW) and drainage only. PATIENTS AND METHODS From July to December 2001, all stable patients with haemopericardium diagnosed by SPW, who did not have immediate active bleeding, were subjected to sternotomy to grade the injury using the...

In the application of multiple Carbon Fiber-Reinforced Plastic (CFRP) plates onto a structural steel member, stepping of the CFRP plate ends is often adopted to prevent debonding. This approach requires the nonuniform extension of CFRP plate lengths. In this study, to shorten the length of CFRP plates, a nonuniform overlapping arrangement of several CFRP plate ends was proposed and the theoreti...

Local post-weld heat treatment is used to reduce welding residual stresses. The existing standards have great differences in the selection of width heated band, and heating width, as an important control parameter local treatment, will directly affect quality treatment. In this paper, numerical simulation method simulate process unequal-thickness joints. stress deformation joint with different ...

This study was a retrospective chart review of the cases operated for maxillofacial trauma with plate osteosynthesis in Oral and Maxillofacial Surgery Unit of Khyber College of Dentistry Peshawar, Pakistan, and was designed to evaluate the frequency and various reasons for the removal of the stainless steel plates in maxillofacial trauma patients. It was conducted on patients who were treated w...

We show that for every separable Banach space X, either SPw(X) (the set of all spreading models of X generated by weakly-null sequences in X, modulo equivalence) is countable, or SPw(X) contains an antichain of the size of the continuum. This answers a question of S. J. Dilworth, E. Odell and B. Sari.

Measurement of the effects of helium (from tritium decay) on the weldability of Types 304 and ITER Grade 316LN stainless steel demonstrated the inherent complexities in designing and conducting an experimental program using tritium-charged-and-aged materials to simulate the effects of irradiation-induced helium on weld behavior. Differences in microstructure, surface condition and alloy chemist...

The stress at the support structure of clarification tank is large, which will have a certain impact on whole structure. typical concentration phenomenon cause structural damage and serious harm to steel itself. In order study influence bearing plate seismic response tank, this paper analyzes dynamic by setting different thickness plates connection between column body tank. Based displacement, ...

Based on an actual corrugated steel plate arch bridge, considering soil-structure interaction, by using the finite element program of ANSYS, a 2-D finite element model was set up to analyze the soil pressure and structural deformation under different load conditions in detail. Since this type of structure relies on the soil-structure interaction to share the load, as the structural parameters h...
