摘　　要：点支承玻璃建筑体系在国内的应用越来越广泛,但仍需要进行大量的研究。本文以理论分析影响点式支承玻璃板承载性能的几个重要因素:连接方式、连接情况、孔心边距等为目的,通过有限元计算和实体结构试验研究的方法,着重对影响沉头式点支承玻璃板承载性能的若干因素进行了实测分析。分析结果表明,有限元分析与试验结果符合得较好,证明了所采用的有限元计算模型的可靠性,并得出了在通常的点支玻璃工程中可采用100mm的孔心边距等结论。The main purpose of this paper is to analyze several factors which influence the load carrying properties of the point supported glass plate, such as connection types,connection conditions,distance from hole to edge,etc.Emphasis has been laid mainly on the analysis of the factors which affect the load bearing properties of sunk typed point supported monolayer glass plates by finite element calculation and experimental measuring method.The comparison shows that finite element calculations agree well with the experimental results,which demonstrates the correctness of the calculation model.Some conclusions,including the recommended distance trom hole to edge to be 100mm in common construction conditions,are drawn.
