【摘要】：超高層建筑的抗震設(shè)計(jì)已從傳統(tǒng)的承載力設(shè)防設(shè)計(jì)逐漸轉(zhuǎn)向了更精細(xì)化的抗震性能設(shè)計(jì)。為滿足實(shí)際高層建筑多層次、過程化的性能目標(biāo),有必要對結(jié)構(gòu)體系進(jìn)行少遇或罕遇地震下的更為真實(shí)精細(xì)的全過程動(dòng)力彈塑性時(shí)程分析。高性能的通用非線性分析軟件通常是實(shí)現(xiàn)這種全過程精細(xì)分析的主要工具,那么,如何有效應(yīng)用該工具開展精細(xì)化分析,以檢驗(yàn)相關(guān)性能目標(biāo)是否達(dá)到預(yù)設(shè)目標(biāo),是實(shí)現(xiàn)基于性能設(shè)計(jì)亟需解決的難題之一。 本文以一幢位于8度設(shè)防區(qū)域、216m高的昆明螺螄灣中心樓超高層建筑為工程案例。首先根據(jù)性能化設(shè)計(jì)思想確定了該建筑的抗震性能指標(biāo)；然后應(yīng)用ABAQUS軟件對該建筑進(jìn)行了罕遇地震下的彈塑性全過程行為的非線性分析,獲得了結(jié)構(gòu)在大震作用下的基底剪力、剪重比、層間位移角、頂點(diǎn)位移,以及核心筒剪力墻、鋼管混凝土柱和其他鋼構(gòu)件、加強(qiáng)層鋼支撐、鋼筋混凝土樓板等的塑性變形與損傷情況、鋼筋屈服情況等彈塑性動(dòng)力響應(yīng)和損傷模式。并對照預(yù)定的性能指標(biāo)對結(jié)構(gòu)體系進(jìn)行了全方位的性能評價(jià)。論文最后基于ABAQUS平臺開發(fā)了將常用結(jié)構(gòu)設(shè)計(jì)模型轉(zhuǎn)化為ABAQUS模型的自動(dòng)轉(zhuǎn)換程序,并進(jìn)行了實(shí)例檢驗(yàn)和應(yīng)用。 論文結(jié)果顯示,合理應(yīng)用ABAQUS軟件能夠?qū)崿F(xiàn)超高層建筑基于性能設(shè)計(jì)的彈塑性精細(xì)化有限元分析,檢驗(yàn)結(jié)構(gòu)在罕遇地震作用下的性能目標(biāo)；本文開發(fā)的ABAQUS結(jié)構(gòu)模型轉(zhuǎn)換程序不僅具有很高的計(jì)算效率,而且可獲得與手動(dòng)轉(zhuǎn)換十分一致的結(jié)構(gòu)彈塑性受力和變形精細(xì)分析結(jié)果。
[Abstract]:The aseismic design of super high-rise building has gradually changed from the traditional design of bearing capacity fortification to the more detailed seismic performance design. It is necessary to carry out a more realistic and precise dynamic elastoplastic time-history analysis of structural systems under rare or rare earthquakes. High performance universal nonlinear analysis software is usually the main tool to realize this kind of full-process fine analysis. How to use the tool effectively to carry out fine analysis to check whether the performance target can reach the preset target is one of the most difficult problems to be solved in the implementation of performance-based design. In this paper, a super high-rise building located at 216m high in an 8-degree fortification area is taken as an engineering case. The aseismic performance index of the building is first determined according to the performance-based design idea. Then the nonlinear analysis of the elastoplastic behavior of the building under rare earthquake is carried out by using ABAQUS software, and the base shear force, shear weight ratio, interstory displacement angle, vertex displacement and core tube shear wall are obtained. Plastic deformation and damage of concrete-filled steel tubular columns and other steel members, reinforced steel supports, reinforced concrete floors, etc. The elastoplastic dynamic response and damage mode of steel bar, such as yield condition, etc. The comprehensive performance evaluation of the structure system is carried out in comparison with the predetermined performance index. Finally, based on the ABAQUS platform, the commonly used structural design model is developed to transform the structural design model into one. For the automatic conversion of the ABAQUS model, A case study and application are carried out. The results show that the application of ABAQUS software can realize the elastic-plastic fine finite element analysis of super high-rise building based on performance design, and test the performance target of the structure under rare earthquake. The ABAQUS structural model conversion program developed in this paper not only has high computational efficiency, but also can obtain the fine analysis results of elastic-plastic force and deformation of structure in accordance with manual transformation.
