［摘要］從概念設(shè)計(jì)出發(fā)，闡述了高烈度區(qū)建筑結(jié)構(gòu)設(shè)計(jì)“兩階段，三水準(zhǔn)”抗震設(shè)計(jì)思想。豎向構(gòu)件是結(jié)構(gòu)在大震作用下維系結(jié)構(gòu)整體穩(wěn)定的基石，須確保豎向構(gòu)件在大震作用下內(nèi)力重分布后仍具有足夠的承載力。因此，“強(qiáng)剪弱彎”、“強(qiáng)柱弱梁”、“強(qiáng)墻肢弱連梁”是確保結(jié)構(gòu)在大震作用下裂而不倒的延性措施。對(duì)彈塑性動(dòng)力時(shí)程分析的結(jié)果“相對(duì)最佳”的合理性判別以及對(duì)柱端實(shí)際受彎承載力相適應(yīng)的抗震受剪承載力的調(diào)整，是保障框架柱不出現(xiàn)柱鉸機(jī)構(gòu)的關(guān)鍵。“耗能元件”和梁端“屈服區(qū)”運(yùn)用“抗”、“調(diào)”相結(jié)合的“強(qiáng)剪弱彎”的措施是確保結(jié)構(gòu)耗能和傳力途徑通暢的技術(shù)保證。

Main structure design of an office building in the earthquake fortification region of 9 intensity

Abstract:Starting from the conceptual design of earthquake, the anti-seismic design thought of ‘two stages and three levels’ for architectural structure design in high intensity region is elaborated. As vertical members are the foundation for structure to maintain integral stability of structure under strong seismic effect, it is important to ensure the vertical member to maintain enough bearing capacity after redistribution of internal force under strong seismic effect. Therefore, ‘strong shear and weak bending’, ‘strong column and weak beam’ and ‘strong wall bracing and weak connection beam’ are the ductility measures to ensure no collapse of structure even if cracked under strong seismic effect. And it is the key for no occurrence of hinge mechanism at the frame column to perform rationality discrimination to the ‘relatively optimal’ result in elastic-plastic dynamic time analysis, as well as adjustment to the antiseismic shear capacity adapted to the actual flexural capacity at the column hinged end. With the measure of ‘strong shear and weak bending’ combining ‘anti’ and ‘adjustment’ for ‘the energy-consuming elements’ and beam end ‘yielding region’ is the technical assurance to ensure structural energy consumption and smooth path for load transferring.
Keywords:conceptual design; displacement; rigidity; ductility
