 [摘要] 基于大型通用有限元軟件ABAQUS對(duì)一棟20層的框架核心筒結(jié)構(gòu)的不同樓板模型進(jìn)行了罕遇地震下的彈塑性時(shí)程分析，并對(duì)比不同樓板模型對(duì)彈塑性時(shí)程分析的影響。具體過(guò)程為：在結(jié)構(gòu)設(shè)計(jì)軟件YJK中進(jìn)行設(shè)計(jì)和配筋，確保各項(xiàng)指標(biāo)符合規(guī)范要求。然后將包括配筋的結(jié)構(gòu)模型轉(zhuǎn)入ABAQUS中，其中樓板分別按剛性樓板、彈性樓板、彈塑性樓板進(jìn)行轉(zhuǎn)換。并考慮了結(jié)構(gòu)的幾何非線性和材料非線性，材料本構(gòu)均按照規(guī)范要求輸入，混凝土梁元采用基于規(guī)范要求編寫(xiě)的Vumat。在驗(yàn)證模型轉(zhuǎn)換正確后進(jìn)行彈塑性時(shí)程分析，并從基底剪力、樓層剪力、層間位移角、節(jié)點(diǎn)位移、破壞發(fā)展?fàn)顟B(tài)以及計(jì)算耗時(shí)等方面對(duì)比了三個(gè)模型間的差異，為結(jié)構(gòu)在ABAQUS中進(jìn)行彈塑性時(shí)程分析提供參考意見(jiàn)。

Abstract: Through elasto-plastic time history analysis under the rare earthquake for a block of 20 layers of frame coretube structure under different slab model based on the large universal finite element software ABAQUS, Comparing with different floor model's influence on the elastoplastic time history analysis. For the specific process:  Designing and reinforcementing in the structural design software YJK, ensure that the indicators meet the code requirements. Then transform the model which is included reinforcement into ABAQUS, it including rigid floor, elastic and elastic-plastic floor and considering the structure geometric nonlinearity and material nonlinearity, The material constitutive are accordance with the code requirements and concrete beam adopt Vumat edited based on the requirement of code. Proceeding elastoplastic time history analysis after the verification of model transformation is correct, Comparing the differences between the three models from the base shear, floor shear, interlayer displacement angle, node displacement and state of damage development and computing time ,provides some guidance in engineering of the elastic-plastic time history analysis for the structure in ABAQUS.

Keywords: frame-core wall structure; elastic-plastic time-history analysis; YJK; ABAQUS; slab calculation model
