豪塞尔(Holzer)法可以计算框架结构各个振型的频率和地震力;当需考虑节点转动时,可先按武藤清氏的D值法,算出框架各层层间剪切刚度后再进行。经比较,其计算结果是相当精确的。本文将其推广应用于地基与上层框架的共同工作。为了进一步提高计算效率,我们利用夏普(sharp)EL-5002型计算器,编制小程序计算。一、多质点简单联系振动系统的自由振动我们先叙述多质点简单联系振动系统的自由振动情况。如图1是由弹簧联系起来的N个集中质点M_i组成的振动系统。其最后
The Holzer method can calculate the frequency and seismic force of each mode shape of the frame structure. When considering the rotation of the node, first calculate the shear stiffness between the layers of the frame according to the D value method of Wutzu Qingshi. After comparison, the calculation results are quite accurate. This article applies its promotion to the joint work of the foundation and the upper framework. To further improve computational efficiency, we use the sharp EL-5002 calculator to compile small program calculations. First, multi-mass simple contact with the free vibration of the vibration system We first describe the multi-mass point simply contact the free vibration of the vibration system. Fig. 1 is a vibration system consisting of N concentrated particles M_i linked by a spring. Its last
