This paper examines the behaviour of circular steel tubes infilled with concrete incorporating recycled rubber particles. The rubberised concrete-filled are tested under lateral cyclic deformations and without co-existing axial loading. A detailed account tests on twelve specimens is provided together complementary material section tests. replacement ratio varied up to a relatively high value 6...

Midkine is a heparin-binding di-domain growth factor, implicated in many biological processes as diverse as angiogenesis, neurogenesis and tumorigenesis. Elevated midkine levels reflect poor prognosis for many carcinomas, yet the molecular and cellular mechanisms orchestrating its activity remain unclear. At the present time, the individual structures of isolated half domains of human midkine a...

To investigate the seismic behavior of wall pier a covered bridge, multi-layer shell element in OpenSEES was used to carry out numerical analysis under horizontal low cyclic loading weak axis direction. The effects mesh divisions models were evaluated and hysteretic curves, skeleton bearing energy dissipation capacity, stiffness degradation displacement ductility with different lateral modes ma...

Abstract Instability-induced wrinkle patterns of thin sheets are ubiquitous in nature, which often result origami-like that provide inspiration for the engineering origami designs. Inspired by instability-induced patterns, we propose a computational design method based on nonlinear analysis loaded and topology optimization. The bar-and-hinge model is employed structural analysis, added with dis...
