【摘要】：結(jié)合基于性能的抗震設(shè)計思想，本文研究了中美兩國關(guān)于鋼筋混凝土（RC）框架-核心筒結(jié)構(gòu)抗震設(shè)計方法的異同以及連梁性能參數(shù)變化對整體結(jié)構(gòu)抗震性能的影響。主要研究工作和成果如下： （1）以一座位于8度（0.2g）的典型RC框架-核心筒結(jié)構(gòu)的抗震設(shè)計為例，介紹了如何根據(jù)中美兩國的抗震規(guī)范進行抗震設(shè)計，比較了兩設(shè)計方案結(jié)構(gòu)的地震效應(yīng)及典型構(gòu)件配筋的差異，結(jié)果表明：中美兩方案結(jié)構(gòu)的設(shè)計地震作用水平相當；按照美國規(guī)范設(shè)計的結(jié)構(gòu)，連梁承載力低于中方設(shè)計方案，剪力墻約束邊緣構(gòu)件箍筋配筋量大，約束范圍大。 （2）在Perform3D中，建立了適用于RC框架-核心筒結(jié)構(gòu)抗震性能評估的梁柱、剪力墻與連梁的彈塑性分析模型，完成了多個RC平面框架、RC框架柱、RC剪力墻與連梁試件的模擬分析，模擬結(jié)果與試驗結(jié)果比較符合，表明所建議模型對于分析RC結(jié)構(gòu)基本構(gòu)件具有較高的準確性，計算效率高。 （3）建立了按中美抗震設(shè)計要求分別設(shè)計的RC框架-核心筒結(jié)構(gòu)的彈塑性分析模型，完成了結(jié)構(gòu)的靜、動力彈塑性分析，比較了中美兩國在模擬地震地面運動輸入、設(shè)計罕遇地震作用下抗震性能差異等。結(jié)果表明：兩結(jié)構(gòu)在峰值荷載前地震響應(yīng)基本一致，在峰值荷載后由于構(gòu)件配筋形式與配筋數(shù)量等差異，結(jié)構(gòu)損傷程度不同；兩結(jié)構(gòu)均滿足各自對應(yīng)的抗震設(shè)計要求，結(jié)構(gòu)構(gòu)件屈服的次序依次為連梁、框架梁、墻肢、框架柱，符合結(jié)構(gòu)抗震設(shè)計預(yù)期，美方設(shè)計方案的連梁屈服早于中方的設(shè)計方案；中方設(shè)計方案的最大層間位移角大于美方設(shè)計方案；中方設(shè)計方案連梁沒有超過生命安全狀態(tài)(LS)，美方設(shè)計方案的連梁變形狀態(tài)介于生命安全狀態(tài)(LS)與接近倒塌狀態(tài)(CP)之間；兩個方案底層墻肢邊緣構(gòu)件豎向鋼筋的最大拉應(yīng)變分布接近，，均達到屈服水平。 （4）以滿足中國抗震設(shè)計要求的RC框架-核心筒結(jié)構(gòu)為對象，研究不同連梁力學性能參數(shù)對整體結(jié)構(gòu)抗震性能的影響，獲得了結(jié)構(gòu)實現(xiàn)震后正常使用功能快速恢復(fù)要求時對可更換耗能連梁承載力和變形能力的需求，為相關(guān)構(gòu)件研究與選用提供參考。探索了采用輕質(zhì)水平結(jié)構(gòu)體系及無梁預(yù)應(yīng)力樓蓋后對整體結(jié)構(gòu)抗震性能的影響。
[Abstract]:Based on the performance - based anti - seismic design idea , this paper studied the effects of the variation on the seismic behavior of the whole structure by the variation of the seismic design method of the RC frame - core barrel structure and the change of the performance parameters of the continuous beam on the seismic performance of the whole structure . The main research work and the results are as follows :

( 1 ) Taking an anti - seismic design of a typical RC frame - core barrel structure at 8 degrees ( 0.2 g ) as an example , this paper introduces how to design the seismic design based on the seismic code of the two countries , compares the seismic effect of the two design schemes and the difference of typical structural reinforcement . The results show that the design seismic action level of the two schemes is comparable ;
According to the structure of the American code design , the bearing capacity of the connecting beam is lower than that of the Chinese design , and the constraint edge component of the shear wall is large in reinforcement amount and large in constraint range .

( 2 ) Based on the elastic - plastic analysis model of RC frame , RC frame column , RC shear wall and continuous beam test piece , the simulation results of RC plane frame , RC frame column , RC shear wall and continuous beam test piece are established . The simulation results are consistent with the experimental results . It is shown that the proposed model has high accuracy and high efficiency for analyzing the basic components of RC structure .

( 3 ) Based on the elastic - plastic analysis model of RC frame - core barrel structure designed according to the requirements of Chinese and American seismic design , the static and dynamic elastic - plastic analysis of the structure is completed . The results show that the seismic response of the two structures is basically consistent before the peak load , and the structural damage degree is different due to the difference of the shape of the structural reinforcement and the number of reinforcement after the peak load .
Both structures meet the corresponding anti - seismic design requirements , and the order of yield of structural members is in turn a continuous beam , a frame beam , a wall limb and a frame column .
The maximum inter - layer displacement angle of the design scheme of the Chinese side is larger than that of the American design scheme ;
The Chinese design scheme has no more than the life safety state ( LS ) , and the deformation state of the connecting beam of the American design scheme is between the life safety state ( LS ) and the near collapse state ( CP ) ;
The maximum tensile and strain distributions of the vertical steel bars at the bottom wall of the two schemes are close to each other and reach the yield level .

( 4 ) In order to meet the requirements of the RC frame - core barrel structure in China ' s anti - seismic design requirements , the influence of the mechanical parameters on the seismic behavior of the whole structure is studied .
