摘　　要：使用有限差分方法,在点支式中空及夹层玻璃抗弯设计方法的基础上探讨点支式中空夹层玻璃的抗弯设计方法.在点支式中空玻璃抗弯设计中考虑宽厚比等尺寸因素的影响,且同时考虑因气温、气压变化而产生的荷载;在点支式夹层玻璃的抗弯设计中适当考虑了PVB(聚乙烯缩丁醛)层的作用.将中空夹层玻璃视为包含着夹层的中空玻璃,从而得到其抗弯设计方法.该设计方法计算结果与试验结果在一定程度上吻合,具有一定的实用价值.The finite difference method was used to the point-supported insulating-laminated glass unit bending loading design which is based on the point-supported insulating glass unit and laminated glass unit design. The size factor（such as width to thickness ratio）, temperature and barometric variations have been taken into account in the point-supported insulating glass unit design. The PVB interlayer＇s contribution has been appropriately considered in the point-supported laminated glass unit design. The insulating-laminated glass unit has been taken as insulating glass unit containing laminated unit and the design method is thus provided. The calculation results of the design method agree with the experimental, and the applicability of design has been evaluated.
