摘　　要：夹板式幕墙系统是一种新兴的玻璃幕墙体系,且近年来工程实践发展迅速,但其理论与设计方法的研究却远滞后于它的实际应用,尤其是目前的规范尚未对夹板式玻璃板承载性能的设计方法做出规定。本文在试验和大量有限元参数分析工作的基础上,提出了夹板式单层玻璃板面外受弯、面内局部承压以及压弯共同作用的受力性能简化设计方法,通过设计方法与试验结果的对比,进一步论证了简化设计方法的有效性。As a new type of glass curtain wall system, recently the overlapped glass curtain wall has found extensive applications in engineering practices, but the researches on the theories and the design methods far lag behind its engineering application, especially the lack of design formulas for its capability calculation in current code. On the basis of the experiments and adequate parametric analysis by FEM, simplified design formulas are proposed for the loading capability of single-layer glass panels restrained by spoke-shaped hollow connectors and square-shaped solid connectors under out-of-plane load, in-plane load, as well as combination of compression and moment actions. Moreover, they are proved to be effective when compared to the experimental results.
