高层建筑中空玻璃幕墙的结构分析

Structural Analysis for Mid-air Glass Curtain-walls in High-rised

运用正交各向异性大挠度板的非线性理论 ,讨论了高层建筑中空幕墙玻璃结构的力学计算问题。根据实际的变形状态导出了相应的控制方程 ;探讨了中空玻璃幕墙的主刚度和折算刚度的计算 ;研究了中空玻璃在自重、风荷载、地震作用力及温度变化情况下的内力和变形的计算方法。所给出的算例与文献 [3]吻合较好。

This paper deals with the problems of mechanical calculation of mid-air glass c urtain-walls in high-rises by using the theory of large deflection of orthotr opic plates. According to practical deformation, the author deduced related con trol equations, discussed the calculations of main reduced stiffnesses and stud ied the inner forces and deformation under the conditions of dead weight, wind l oad, seismic force and temperature changes.
