［摘要］以我國最近5年設(shè)計(jì)建造的高層框架-核心筒結(jié)構(gòu)為背景，研究了7度區(qū)（0-1g）框架-核心筒結(jié)構(gòu)概念設(shè)計(jì)中的若干關(guān)鍵問題以及相應(yīng)的設(shè)計(jì)控制指標(biāo)，主要包括核心筒與樓層的面積比值、核心筒的高寬比、核心筒的外墻厚度與內(nèi)墻厚度、核心筒的外墻開洞、框架柱和框架梁的截面尺寸以及樓板厚度等。從結(jié)構(gòu)力學(xué)性能的角度出發(fā)，通過算例分析并結(jié)合工程設(shè)計(jì)經(jīng)驗(yàn)，給出了框架-核心筒結(jié)構(gòu)概念設(shè)計(jì)中主要設(shè)計(jì)控制指標(biāo)的取值建議，以供工程設(shè)計(jì)人員參考。

Abstract:Based on the high-rise frame-corewall structures designed and constructed in the last five years in China, several critical issues and corresponding design control indexes in the conceptual design of frame-corewall structure in region of 7-degree seismic precautionary intensity with seismic acceleration of 0-1g were studied, including the area ratio of corewall to floor, the height-width ratio of corewall, the thickness of outer wall and inner wall of corewall, the opening of the outer wall of the corewall, the section size of the frame column and the frame beam, and the thickness of the floor slab. From the point of view of structural mechanical performance, the example analysis was used to combine engineering design experience, and the value proposals of main design control indexes in the conceptual design of frame-corewall structure were given for reference of engineering designers.

Keywords:frame-corewall structure; mechanical performance; conceptual design method
