摘　　要：为满足现代木结构建筑楼盖结构的安全性和舒适性的客观要求,本研究对一栋二层轻型木结构建筑示范房楼盖结构开展了集中荷载下的挠度值测试,以及静态均布荷载、集中荷载挠度值的ANSYS软件模拟计算验证与分析工作,其模拟值验证了测试值的正确性。主要结论表明,在均布荷载主要为楼盖自重,且楼盖设计的均布荷载标准值0.566 kN/m的情况下分别得到的模拟最大挠度值均符合FHA标准;在1kN集中荷载下模拟楼盖挠度最大值在其中点(5号)处,并满足轻型木结构楼盖系统建筑规范规定;其最大测试值与预测最大值的相对误差为14.8%;1 k N集中荷载下模拟6条挠度值测试线均呈现抛物线分布,且左右对称。上述研究对木结构建筑楼盖结构的优化设计和评价工作具有工程应用意义。In order to meet the objective requirements of the safety and comfort of modern wooden structure building structure,the paper carried out the deflection test under the concentrated load and the static uniform load on the structure of a two-storey light wooden structure demonstration building. The concentrated load deflection value was simulated and verified by ANSYS software,and its simulation value verified the correctness of the test value. The main conclusions showed that the simulated maximum deflection values obtained under the uniform load of the floor are mainly the weight of the floor and the uniform load value of the floor design is 0.566 kN/m,which are consistent with the FHA standard;The simulation is carried out under the concentrated load of 1 kN. The maximum deflection of the floor is at the midpoint (No.5)and meets the building code requirements for the light wood structure floor system;Under the concentrated load of 1 kN,the maximum deflection of the simulated floor is at the midpoint(No.5)and meets the building code specification for the light wood structure floor system;The relative error between the maximum test value and the predicted maximum value is 14.8%;The 1 kN concentrated load test curves of the six simulated deflection values are all parabolic and symmetric. The above research has engineering application significance for the optimization design and evaluation of floor structure for wooden structure building.
