This paper presents a dynamic nonlinear numerical simulation of a 5-story full-scale steel frame structure based on Perform-3D. Flexibility-based fiber element and Maxwell model are adopted for structure member simulation after a post analysis of the shaking table test of a 4-story full-scale steel frame. The author simulates the low cyclic reciprocating load test for the steel members with fib...

PURPOSE The introduction of the klapskate in speed skating confronts skaters with the question of how to adjust the position of the hinge in order to maximize performance. The purpose of this study was to reveal the constraint that klapskate hinge position imposes on push-off performance in speed skating. METHOD For this purpose, a model of the musculoskeletal system was designed to simulate ...

Abstract Under strong earthquakes, reinforced concrete (RC) walls in high-rise buildings, particularly wall piers that form part of a coupled or core system, may experience axial tension–flexure loading. In this study, detailed finite element model was developed VecTor2 to provide an effective tool for the further investigation seismic behaviour RC subjected tension and cyclic lateral The verif...

PURPOSE To describe the effect of prolonging the standard suction duration during laser-assisted in-situ keratomileusis (LASIK) and its effect on flap thickness and hinge length using sub-Bowman keratomileusis (SBK) microkeratome. METHODS Fifty-six eyes (28 patients) were included and divided into 2 groups; Group-A: eyes with flatter corneas (36 eyes, 18 patients) and mean keratometric readin...

Numerical simulations have been widely used to study the inelastic response of reinforced concrete structures under earthquake loading. Yet, due to the complex nature of structural inelastic behavior, experimental results are often required to verify the efficiency of applied numerical schemes. In this paper, experimental results of bare reinforced concrete frame models are employed to validate...

In many countries of moderate to high seismicity, reinforced concrete (RC) core walls are used as lateral bracing systems in midto high-rise buildings where they typically accommodate lift shafts or stair cases. Unlike planar walls which provide horizontal strength and stiffness mainly in the in-plane direction of the wall, core walls provide bidirectional strength and stiffness. This feature c...

Current design codes require long bar development length and high joint hoop ratio in reinforced concrete (RC) exterior beam-column joints using high-strength materials, which reduces constructability. This study investigated the seismic behavior of RC with insufficient hoops beam flexural bars (Grade 600 MPa) and/or concrete. Six half-scale were tested under cyclic load reversals. The test par...
