本文根据厂房屋盖体系以剪切变形为主的理论,对均匀拔柱单层厂房的自由振动理论进行了研讨,给出了理论分析公式,并用此公式计算了一座冶金企业的拔柱厂房,计算结果与实测数据相当接近。这种特殊类型单层厂房的理论分析和实测结果的一致性,再一次支持了以剪切变形为主的单层厂房动力和静力分析理论。 Based on the shear-deformation theory, the paper studies the theory of free vibration of a uniform-picked-storey single-storey factory building, gives the theoretical analysis formula, and uses this formula to calculate a pillar factory of a metallurgical enterprise. The calculated results are quite close to the measured data. The consistency of the theoretical analysis and the actual measurement results of this special type single storey building once again supports the dynamic and static analysis theory of a single storey building dominated by shear deformation.
