根据厚板的位移模式 ,构造了空腹夹层板超级单元 ,该单元在保证高精度的同时 ,可大大减少自由度。利用空腹夹层板超级单元与常规的柱单元形成的混合元 ,可分析空腹夹层板柱结构。对一多层空腹夹层板柱结构的动力特性作了现场测试试验 ,并与理论值比较 ,二者吻合较好
According to the displacement pattern of the slab, the sandwich plate super-unit is constructed. This unit can greatly reduce the degree of freedom while ensuring the high precision. Fasting sandwich plate columns can be analyzed using a mixed element formed by a fasting sandwich plate super unit and a conventional column unit. Field experiments on the dynamic characteristics of a multi-layer sandwich plate structure were carried out, and the results were in good agreement with the theoretical values
