转角型幕墙铝板风荷载作用下内力和变形的数值模拟

摘要

阐述了转角型铝板和加劲肋构成的铝板幕墙的内力及变形计算，采用ANSYS软件，对板块由转角型铝板与5条加劲肋组成的复合结构的内力和变形进行计算，研究了加劲肋与铝板转角处由于局部铆钉松脱由刚结点变成铰接点后，其计算模型发生改变的应力及位移计算，最后介绍实际应用。%Using the ANSYS software, the internal force and displacement of the corner type plate structure which are composed of the trough type aluminum plate and 5 stiffening ribs are calculated. The stiffening rib and the aluminum plate corner partial rivet loosens by the rigid joint turns the hinge point is studied. The computation model is built and its biggest internal force and displacement are obtained. Finally,the practical application is introduced.
