Goals of this preliminary study are to better understand (1) earthquake performance of wood-frame shear walls carrying gravity loads, compared with walls without gravity load, and (2) performance of walls subjected to a sequence of earthquake motions, compared with walls subjected to a single earthquake. Tests with simulated earthquake ground motions were conducted on 2,440 by 2,440-mm (8 by 8-...

Abstract This paper investigates the weight minimization of stiffened panels simultaneously optimizing sizing, layout, and topology under stress buckling constraints. An effective optimization parameterization is presented using multiple level-set functions. Plate elements are employed to model panels. The stiffeners parametrized by implicit internal topologies optimized as well their layout. A...

the increase of cell temperature with increased irradiance is probably the mostsignificant disadvantage of using photovoltaic modules equipped with booster reflectors. the aimof this study is to investigate the possibility of improving the performance of a photovoltaic waterpumping system by using a booster reflector and to keep the temperature of pv panels at a lowlevel by cooling pv panels wi...

Abstract This paper presents the shear behavior, crack patterns, and failure modes of reinforced concrete beams strengthened with geopolymer Portland cement mortar panels. The specimens were prepared in form panels a size 300 mm x 700 mm, each consisting 4 pieces. specimen produced dimension 150 2300 static monotonic loading test was carried out. To ensure strength used is based on target, comp...
