选择高度为118,150,177m的三个工程实例,分别采用钢筋混凝土框架-核心筒结构体系和混合框架-钢筋混凝土核心筒混合结构体系进行设计和计算,对两种结构体系进行了技术和经济两方面的对比和分析。探讨了两种结构体系随高度增加显现出的规律和经验。对比结果显示:混合结构体系的结构质量减小20%,风载效应增大10%,地震效应减小15%～25%,工程总造价增加10%～12%,有效使用面积和楼层净高度增加、施工速度更快、抗震性能好,综合而言,混合框架-核心筒结构体系具有一定优势。
Three engineering examples with height of 118,150,177m were selected and designed and calculated respectively by reinforced concrete frame-core tube structure system and hybrid frame-reinforced concrete core tube mixed structure system. The two structural systems were technically and economically optimized Comparison and analysis. The regularities and experiences of two kinds of structural systems with increasing height are discussed. The results show that the structural quality of the hybrid system is reduced by 20%, the wind load effect is increased by 10%, the seismic effect is reduced by 15% -25%, the total cost of the project is increased by 10% -12%, and the effective use area and floor height Increase, construction faster, good seismic performance, comprehensively speaking, hybrid frame - core tube structure system has some advantages.
