摘　　要：本文分别对点支式中空和夹层玻璃进行了承载性能试验,得出了点支式中空和夹层玻璃的荷载-位移及荷载-应力曲线以及点支式夹层玻璃在一定荷载作用下位移和应力随时间变化的关系曲线。试验结果表明:点支式中空玻璃和夹层玻璃随着荷载的增加,荷载-位移、荷载-应力变化曲线接近于线性;现行国家规程关于点支式中空玻璃和夹层玻璃位移和应力的计算值大于试验值,偏于保守。对规程有关点支式中空玻璃和夹层玻璃厚度取值的问题做进一步探讨是完全必要的;点支式夹层玻璃的位移和应力受荷载持续时间的影响较大。本文的试验结果可为规程的修订和工程设计提供参考。Experimental research was carried out on load bearing capacity of point supported mid hollow and laminated glasses. From tests the load displacement, load stress curves of point supported mid hollow and laminated glasses were obtained, and the relation curves of displacements and stresses changed with time for point supported laminated glasses were obtained as well. The experimental results indicated that with the increase of load, the load displacement, load stress curves of point supported mid hollow and laminated glass approached to be linear. Displacement and stress of point supported laminated glasses was greatly affected by loading time. Comparison of experimental results with calculated ones indicates that the current design code will lead to conservative results, and the equivalent thickness of point supported mid hollow and laminated glasses provided in the code should be further discussed.
