Research ArticleOpen accessIn the abstractFinite Element Simulation and Parametric Studies of Perfobond Rib ConnectorSuhaib Yahya Kasim Al-Darzi, Ai Rong Chen, Yu Qing LiuSimulating the push-out test and conducting parametric study using finite element model are conducted using perfobond connectors. The finite element model was verified through comparing with push-out test results. The verified finite element model was then used to conduct parametric study aiming to investigate the effect of several parameters, such as height and thickness of connector, cross sectional area and … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 8,218 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFinite Element Study Using FE Code (PLAXIS) on the Geotechnical Behavior of Shell FootingsBujang B.K. Huat, Thamer A. MohammedThis study describes a study on the geotechnical behavior of shell footing using a non-linear finite element analysis with a finite element code, PLAXIS. The shell footing is found to have a better load carrying capacity compared with the conventional slab/flat footing of similar cross sectional area. The FE analysis also showed a reasonably good agreement with the laboratory experimental … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,884 accessesView PDF Cite
