【摘要】 利用有限元方法,求解四点背栓式支承石材幕墙背栓开孔处的最大应力,讨论了孔边最大应力对于石材幕墙承载性能的影响,指出背栓开孔直径、深度及石材厚度对于孔边应力的影响,对背栓式石材幕墙的设计做出了合理的建议。更多还原

【Abstract】 The authors calculates the maximum around-the-hole stresses of the back-bolt stone curtain units with finite element method,and discusses its effect on the bearing property.This paper points out that the diameter、deepness of backbolt hole,and the thickness of the stone panel have influence on the around-the-hole stresses distinctly.Some advices for the design work are proposed.更多还原
