Susceptibility of flexure-dominated reinforced concrete walls to premature compression failure modes (global lateral instability, local rebar buckling, etc.) was exposed during the recent past earthquake events in Chile and New Zealand. Numerous experimental studies have been conducted since then on isolated columns representing wall boundary zones study critical parameters influencing these mo...

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...

born on the 15 of October, 1986 in Amsterdam. After graduating high school (Bilingual VWO, Berlage Lyceum, Amsterdam, cum laude) in 2005, he studied medicine at the Vrije Universiteit in Amsterdam. During his studies in 2008, he became involved in spine research through a one-year research internship within the PhD project of dr. R.J. Kroeze, “Adipose stem cells on a biodegradable polymer for s...

the residual stresses in composite laminates depend on several factors including the conditions of fabricating process, property of materials, direction and lay-ups of the layers. however the thermo-elastic behavior of composite is one of the most important parameters affecting the magnitude of residual stresses. the elastic properties and residual stresses do not remain constant under cyclic t...

Cyclic loading–induced deformation of soil is a common problem in engineering practice. In current practice, however, monotonic triaxial tests are more commonly used due to the availability apparatus and ease operation. Thus, it would be very useful practical if could evaluate behavior under cyclic loading. This study aims find an explicit relationship between saturated soft clay. Six nine comp...

Effect of Mean Stress on Low-Cycle Fatigue Strength of a Medium Carbon Steel S45C True Stress-Controlled Cyclingby Tatsuo ENDO*, Shoji HARADA*, Yoshihiro FUKUSHIMA* and Haruo SAKAMOTO** Nominal stress-controlled low-cycle fatigue life under imposed mean stress is affected by elongation or contraction due to cyclic stress-induced creep. Therefore, the effect of mean stress was examined by a micr...

Finite element analysis of a tubular T-joint subjected to various loading conditions including pure axial loading, pure in-plane bending (IPB) and different ratios of axial loading to in-plane bending loading has been carried out. This effort has been established to estimate magnitudes of the peak hot spot stresses (HSS) at the brace/chord intersection and to find the corresponding locations as...

The design of a thin-walled composite beam is presented whose purpose to facilitate the study intra-laminar tunneling cracks at sub-structural length-scale. utilizes variable thickness reinforcement in longitudinal direction develop gauge zone near-uniform strains when loaded cantilever configuration. manufactured from E-glass fibers and epoxy resin tested under static cyclic multi-axial loadin...

PURPOSE The purpose of this study was to investigate the effects of implant tilting and the loading direction on the displacement and micromotion (relative displacement between the implant and bone) of immediately loaded implants by in vitro experiments and finite element analysis (FEA). METHODS Six artificial bone blocks were prepared. Six screw-type implants with a length of 10 mm and diame...
