摘　　要：清远市科技馆与青少年活动中心A单元结构设计中,通过采用钢桁架和无粘结预应力楼板解决了建筑功能对大跨、大空间的要求。并根据施工仿真,分析了结构各阶段的受力情况,确保了该方案的全过程可行性。最后,对大跨度区域进行了舒适度分析,验证得知楼板竖向振动加速度峰值可满足规范要求。In the structural design of part A of Qingyuan Science and Technology Museum and Youth Activity Center,steel truss and unbonded prestressed slab were applied to meet the architects'requirements of large span and wide space.In addition,according to the construction simulation,the stress of the structure of each stage was analyzed,which ensured the feasibility of the whole process of the scheme.Finally,the comfort degree of the large-span area was analyzed,and it was verified that the peak value of vertical vibration acceleration of the floor could meet the requirements of the code.
