武汉世界贸易大厦工程采用了两端固结超静定无粘结预应力混凝土变截面楼板结构，高跨比达1/52。这种楼板结构可以使弯矩分布合理，并可减轻楼板结构的重量，增大开间。本文简要介绍了该工程楼板结构的局部模型试验研究，建立了无粘结预应力混凝土变截面楼板结构的弹塑性全过程分析方法，计算结果与试验结果吻合较好。
Wuhan World Trade Building project uses a two-end consolidation of statically indeterminate prestressed concrete non-variable cross-section floor structure, high-span ratio of 1/52. This floor structure can make the bending moment distribution is reasonable, and can reduce the weight of floor structure, increase the bay. In this paper, the local model test of the slab structure of the project is briefly introduced, and the elasto-plastic full-process analysis method of the unbonded prestressed concrete slab structure is established. The calculated results are in good agreement with the experimental results.
