为了进一步了解框架-剪力墙结构在地震作用下的动力特性,本文在对框架-剪力墙结构线性抗震分析的基础上,进一步考虑了结构中的非线性理论,强调框架-剪力墙结构的非线性抗震性.本文采用的分析软件是有限元分析软件ANSYS,用软件对框架-剪力墙结构进行非线性的抗震分析,得出了结构在大震作用下结构的变形和内力.分析结果表明,此结构在大震作用下整体稳定性较好,只有局部构件发生塑性变形,不影响结构的安全性. 相似文献

装配式剪力墙结构是建筑产业化发展的趋势，因其可持续性的优点在建筑施工中得到广泛应用。剪力墙墙体之间的竖向接缝对剪力墙结构的抗震效果有直接影响，但目前的接缝施工技术没有统一标准，材料质量不统一等问题制约了装配式建筑剪力墙的抗震性能研究。据此，本研究设计了对不同的竖向接缝剪力墙试件进行试验，探究其受力性能。同时构建有限元分析模型对竖向接缝剪力墙的抗震性能进行分析。试验结果显示，剪力墙结构竖向接缝的相对刚度计算值与试验值之比在0.85～1.05之间，两者高度吻合。由此说明，研究设计的竖向接缝剪力墙的抗震效果较好，对相关的建筑设计具有指导意义。 相似文献

高层建筑结构不应采用全部为短肢剪力墙的剪力墙结构,即只能采用部分短肢剪力墙.对于短肢剪力墙结构的定义,<高规>只明确这种类型结构的剪力墙承受的第一振型底部地震倾覆力矩不宜小于结构总底部地震倾覆力矩的50%,而对于短肢剪力墙较多的剪力墙结构并没有给出一个具体的量化标准.全国各地区也均未给出统一的标准,没有定量的界限来判断短肢剪力墙结构.笔者认为,从概念上说,可以从短肢剪力墙承受结构底部的抗倾覆力矩来判定. 相似文献

This paper presents some methods that the standard acceleration design response spectra derived from the present China code for seismic design of buildings are transformed into the seismic demand spectra, and that the base shear force-roof displacement curve of structure is converted to the capacity spectrum of an equivalent single-degree-of-freedom （SDOF） system. The capacity spectrum method （CSM） is programmed by means of MATLABT.0 computer language. A dual lateral force resisting system of 10-story steel frame-steel plate shear walls （SPSW） is designed according to the corresponding China design codes. The base shear force-roof displacement curve of structure subjected to the monotonic increasing lateral inverse triangular load is obtained by applying the equivalent strip model to stimulate SPSW and by using the finite element analysis software SAP2000 to make Pushover analysis. The seismic performance of this dual system subjected to three different conditions, i.e. the 8-intensity frequently occurred earthquake, fortification earthquake and seldom occurred earthquake, is evaluated by CSM program. The excessive safety of steel frame-SPSW system designed according to the present China design codes is pointed out and a new design method is suggested. 相似文献

INTRODUCTION Adequate information on dynamic soil proper-ties, especially dynamic shear modulus and dampingratio, is essential for accurate computations of groundresponse and soil-structure interaction problems.Many experimental investigations carried out onsandy soils through resonant column test or improvedcyclic triaxial test in early studies (Hardin and Richart1963; Hardin and Black, 1968; Drnevich and Richart,1970; Seed and Idriss, 1971; Kokusho, 1980) showedthat the small … 相似文献

This paper presents the results of an experimental investigation on the response of pre-damaged reinforced concrete (RC) beam strengthened in shear using applied-epoxy unidirectional carbon fiber reinforced polymer (CFRP) sheet. The reasearch included four test rectangular simply supported RC beams in shear capacity. One is the control beam, two RC beams are damaged to a predetermined degree from ultimate shear capacity of the control beam, and the last beam is left without pre-damaged and then strengthened with using externally bonded carbon fiber reinforced polymer to upgrade their shear capacity. We focused on the damage degree to beams during strengthening, therefore, only the beams with side- bonded CFRPs strips and horizontal anchored strips were used. The results show the feasibility of using CFRPs to restore or increase the load-carrying capacity in the shear of damaged RC beams. The failure mode of all the CFRP-strengthened beams is debonding of CFRP vertical strips. Two prediction available models in ACI-440 and fib European code were compared with the experimental results. 相似文献

In order to evaluate the seismic behavior of confined RC column-composite beam joints, five interior joints were tested under low cyclic reversed load. The weakening extent of flanges, the number of studs, and whether to reinforce weakened flanges were used as parameters in designing these five joints. Failure characteristics, hysteretic curves, skeleton curves, ductility, energy dissipation, strength degradation, and stiffness degradation were analyzed. The test results revealed that the steel beam flanges in the joints were equivalent to the tie rod. Weakened flanges resulted in poor seismic behavior; however, the seismic behavior could be improved by increasing studs and reinforcing weakened flanges. The joint steel plate hoops, equivalent to stirrups, did not yield when the maximum load was reached, but yielded when the failure load was reached for the joints with shear failure. Increasing stud-type joints and reinforcing flange-type joints ensured good seismic behavior and met project requirements. Based on the experimental results, the failure mechanism of the joints was discussed, and the shear capacity equations of the joints was presented. 相似文献

Reinforced concrete （RC） columns lacking adequately detailed transverse reinforcement do not possess the necessary ductility to dissipate seismic energy during a major earthquake without severe strength degradation. In this paper, a new retrofit method, which utilized fiber-reinforced plastics （FRP） confinement mechanism and anchorage of embedded bars, was developed aiming to retrofit non-ductile large RC rectangular columns to prevent the damage of the plastic hinges. Carbon FRP （CFRP） sheets and glass FRP （GFRP） bars were used in this test, and five scaled RC columns were tested to examine the function of this new method for improving the ductility of columns. Responses of columns were examined before and after being retrofitted. Test results indicate that this new composite method can be very effective to improve the anti-seismic behavior of non-ductile RC columns compared with normal CFRP sheets retrofitted column. 相似文献
