【摘要】 本文介绍了在中国银行总部大厦的结构设计中所进行的大胆探索和创新。根据建筑设计的要求,提出无转换梁柱网转换结构体系,利用层间增设局部墙体对不落地柱进行转换,上下层楼板受力作为拉压平衡条件参加工作,确保了这一新的柱网转换体系的安全可靠;对空间内锥型悬挑结构采用无悬挑梁的板柱悬挑结构体系的结构设计方法,悬挑部分上部新增柱网直接落于挑出的水平楼板和斜墙上,考虑上部结构的整体空间共同作用,同时利用水平楼板受拉与斜墙受压相互平衡,以此解决了悬挑结构不设梁的技术难题;解决超大跨钢桁架上托八层钢筋混凝土结构的综合性设计难题,按施工及使用两个阶段进行分析,综合考虑温度、地震的影响,以及与钢筋混凝土结构共同工作的问题,形成国内不多见的建筑结构形式。更多还原

【Abstract】 The main important innovative structural design of the Bank of China is th e shifting in position of the vertical columns to a horizontal nearby posit ion to meet the architectural design requirements.The shifting is carried out through the junction in one intermediate flo or by adding partial reinforced concrete wall and using both the upper and lower floor slabs as tensile and compressive mem bers to reach equilibrium with the sh ifting columns.Careful software an alysis has been made for the incurred stresses d ue to shifting and relevant location s of steel reinforcements have been w ell studied.The second innovative design is the three sided slanting reinfo rced concrete walls which project 9.8meters from each side with a height of 4?8stories.These projecting slabs do not have a ny supports at the projecting ends.On the contrary,there are even columns resting on the top of them nearby the edges of the projecting slabs to support s everal stories.The third innovative desig n is the use of the steel hybrid super-huge trusses that create the large fr ee span facades.The four 55-meter-long tru sses weigh 200tons each.They provid e columnless support for the 8-story executive wings above them.The super-huge tru sses are designed for both the constr uction and service stages in consideration of the comprehensive effects of temperature and earthquake.更多还原
