Abstract
Taken a super high-rise frame-core wall structure as an example,comprehensive optimization of the original structural design calculation parameters,structural loads,walls,columns,beams,plates,roof steel structure brackets and raft foundation was conducted,where the structural stiffness,weight and cost were set as control objectives,while meeting the structural specifications and transfinite review requirements.Comparison of the stiffness,seismic performance and cost between the original design and the optimized one was conductedby PKPM software.The results show that all the indicators meet the specification requirements,and benefits such as reduced structural weight,reduced earthquake action,more reasonable stiffness distribution,increased ductility and structural safety,increased indoor space,shortened construction period and reduced construction cost of 22 million 946 thousand and 800 yuan profit.关键词
