| 摘 要： | 在框架结构动力分析中,往往是把填充墙质量集中在楼层处进行求解.文中考虑填充墙实际分布对结构自振特性的影响,通过传递矩阵法求解结构自振频率和振型,并进一步分析了高阶频率的分布规律.结果表明,与采用集中质量模型的振型叠加法相比,填充墙的竖向质量分布会对框架结构高阶频率产生很大影响；框架结构的高阶模态具有局部性和密集分组的特...

| Abstract: | The masses of infilled walls are always concentrated at floors in the dynamic analysis of infilled-frame structure.In this paper,we take into account the real mass distribution along the height of structures,the natural frequencies and modes are found by using the method of field transfer matrix.This paper also analyzes the distribution rule of high-order frequencies.It shows that,compared with the modal analysis,which used the lumped-mass distribution model,the mass distribution along the height of structu... |
