摘要(Abstract):

针对洋山深水港商务广场一期工程A楼工程特点,进行了连体结构的概念设计。详细分析了连接部位厚度较大的连体结构的动力特性,计算了小、中震弹性作用下连体结构的楼板应力,同时进行了弹性时程分析。分析结果表明,连体结构具有独特的动力特性,其反向振型对连接部分梁板有较大影响。结构布置应尽量对称及避免结构的高位转换,尽可能减小扭转效应。
Based on engineering characteristics of a building in business plaza of Yangshan Deepwater port first phase project,the concent design of the connecting building are studied.The dynamic analysis of the thick connecting building was done.The stress response of the slab of connecting building to earthquake loading was calculated.At the same time,seismic analysis using step-by-step integration was calculated.The result indicate: many layer connecting building has special dynamic characteristic;the reverse mode has effect on the stress of the connecting beams and planes;the structure should be bilateral symmetry and avoid structural perch conversion to decrease the structural torsion as possible.
