【摘要】：本文在梁柱剛接鋼框架屈曲約束鋼板剪力墻(簡稱R-BRW)體系的基礎(chǔ)上,提出了一種新型的結(jié)構(gòu)體系,即裝配式梁柱鉸接鋼框架屈曲約束鋼板剪力墻(簡稱P-BRW)體系。該結(jié)構(gòu)體系采用柱貫通、梁端鉸接于柱的連接方式,無需現(xiàn)場施焊,符合全預(yù)制裝配化的要求；在地震作用下,柱不受水平力的作用,梁柱節(jié)點不傳遞彎矩,可以大大減小梁柱截面尺寸；水平力由屈曲約束鋼板剪力墻來承擔(dān),充分利用了屈曲約束鋼板剪力墻通過自身屈服來耗散地震能量的優(yōu)勢。為了較全面的研究該新型結(jié)構(gòu)體系的抗震性能,本文做了以下工作：1.采用簡化模型來模擬鋼板剪力墻,屈曲約束鋼板剪力墻采用混合“4-6””模型,普通鋼板剪力墻采用混合“2-8”模型,并利用ANSYS軟件驗證了簡化模型的合理性；2.分別建立了相同梁柱截面尺寸的P-BRW結(jié)構(gòu)、R-BRW結(jié)構(gòu)和梁柱剛接鋼框架普通鋼板剪力墻(簡稱R-W)結(jié)構(gòu)的單榀兩跨10層模型,運用ANSYS軟件對三種模型進(jìn)行不同抗震設(shè)防烈度下的多遇地震彈性分析；選取2組天然波和1組人工波,利用SAP2000軟件對三種模型進(jìn)行不同抗震設(shè)防烈度不同地震波輸入下的罕遇地震動力時程分析。分別得到了三種模型的樓層位移曲線、層間位移角曲線、構(gòu)件出鉸機制、頂點位移時程曲線以及基底剪力時程曲線等。分析結(jié)果表明：在小震下,三種結(jié)構(gòu)的構(gòu)件都處于彈性階段,層間位移角沿樓層的分布都較為均勻,P-BRW結(jié)構(gòu)的抗震性能不如R-W結(jié)構(gòu)的抗震性能；在大震下,R-BRW和R-W結(jié)構(gòu)要早于P-BRW結(jié)構(gòu)在底層柱端出鉸,且P-BRW結(jié)構(gòu)不適宜用于地震設(shè)防烈度8度(0.2g)以上的地區(qū)；3.在上述研究的基礎(chǔ)上,建立了一幢15層P-BRW結(jié)構(gòu)整體分析模型,運用SAP2000軟件對其進(jìn)行不同抗震設(shè)防烈度不同地震波輸入下的罕遇地震動力時程分析,研究了整體結(jié)構(gòu)的抗震性能。經(jīng)研究表明,該新型結(jié)構(gòu)體系在合理的梁柱截面尺寸下,在8度(0.2g)及以下地震設(shè)防烈度的罕遇地震作用下,滿足“大震不倒”的抗震設(shè)防要求,能夠保證梁柱繼續(xù)保持彈性,使梁柱能提供足夠的恢復(fù)力,以實現(xiàn)整體結(jié)構(gòu)在震后的“自復(fù)位”功能,適合鋼結(jié)構(gòu)建筑工業(yè)化的發(fā)展要求。
[Abstract]:In this paper, a new structure system is proposed on the basis of Liang Zhu rigid steel frame buckling restrained steel plate shear wall (R-BRW) system. The assembled Liang Zhu hinged steel frame buckling restrained steel plate shear wall (P-BRW) system. The structure system adopts the connection mode of column through, beam end hinged to column, does not need to be welded on the spot, and meets the requirements of full precast assembly. The column is not subjected to horizontal force, Liang Zhu node does not transfer bending moment, which can greatly reduce the size of Liang Zhu section, and the horizontal force is borne by buckling steel plate shear wall. This paper makes full use of the advantage of buckling restrained steel plate shear wall to dissipate seismic energy through its own yield. In order to study the seismic behavior of the new structural system comprehensively, the following work is done in this paper: 1. The simplified model is used to simulate the steel plate shear wall. The mixed "4-6" model is used for buckling restrained steel plate shear wall and the mixed "2-8" model is used for common steel plate shear wall. The rationality of the simplified model is verified by using ANSYS software. (2) the single two-span 10-story model of P-BRW structure with the same size of Liang Zhu and the common steel plate shear wall (R-W) structure with Liang Zhu rigid-jointed steel frame is established respectively. Using ANSYS software to analyze the seismic elasticity of three kinds of models under different seismic fortification intensity, two groups of natural waves and one group of artificial waves are selected. The dynamic time-history analysis of rare earthquakes with different seismic fortification intensity and seismic wave input is carried out by using SAP2000 software. The floor displacement curves, interstory displacement angle curves, and the mechanism of component hinge are obtained, respectively. The analysis results show that the members of the three kinds of structures are in the elastic stage under the small earthquake. The seismic behavior of P-BRW structure is not as good as that of R-W structure, and that of R-BRW and R-W structures is earlier than that of P-BRW structure at the bottom column under strong earthquake. Moreover, P-BRW structure is not suitable for use in areas where the seismic fortification intensity is above 8 degrees or 0.2 g. Based on the above research, a global analysis model of a 15-story P-BRW structure is established. The dynamic time-history analysis of rare earthquakes with different seismic fortification intensity and seismic wave input is carried out by using SAP2000 software, and the seismic behavior of the whole structure is studied. The results show that the new structure system is of reasonable Liang Zhu cross section size. Under the action of rare earthquakes with earthquake fortification intensity below 8 degrees or 0.2g, to meet the seismic fortification requirements of "large earthquakes will not fail", Liang Zhu will be able to maintain its flexibility and enable Liang Zhu to provide sufficient resilience. In order to realize the function of "self-reset" of the whole structure after the earthquake, it is suitable for the development of the steel structure building industrialization.
