Abstract ：
为研究端板连接不锈钢梁柱节点抗震性能,设计了6个端板连接梁柱节点足尺试件,包括5个不锈钢节点和1个Q345B普通钢节点。对节点试件进行拟静力试验,得到各试件的失效破坏形态、滞回曲线和承载性能等。采用有限元软件ABAQUS对节点试件的低周反复加载试验过程进行准确模拟,进一步分析了节点的抗震性能。结果表明:不同材料牌号不锈钢的中柱节点试件的耗能能力基本相当,且优于普通钢中柱节点试件的;不锈钢中柱节点试件的梁端荷载-位移滞回曲线较边柱节点的更为饱满,但中柱节点试件的承载力较低;设置端板加劲肋可以显著改善节点试件的抗震性能,承载力提高约30%,累积耗能增加100%。节点试件的转角均满足欧洲和美国抗震规...

Abstract ：
A new multiple lateral force resisting system consisting of coupled low-yield-point steel plate shear walls (C-LSPSW) was proposed as a promising alternative to improve the ductility, energy-dissipation capacity, architectural flexibility, and economic efficiency of steel plate shear walls (SPSWs). To investigate its seismic performance and damage behavior, eight C-LSPSW specimens with different configuration parameters, including two different stories and four different section sizes of coupling beams (CBs), were designed and the corresponding numerical models were established by verified modeling approach. The incremental dynamic analyses (IDA) were conducted on these specimens, and the multi-stage damage indices of the C-LSPSW system were proposed based on different damage states. The design suggestions for the C-LSPSW system were proposed in terms of the fragility analyses. The analytical results demonstrated that the ductile damage mechanism with the sequence of "infill plates to CBs or horizontal boundary elements (HBEs) to vertical boundary elements (VBEs)" was achieved more easily in the C-LSPSW system, which gave full play to the superiority of multiple seismic defense lines. Under high seismic excitation, the failure probability of the C-LSPSW system was smaller than that of the LSPSW system, and the coupling superiority was more obvious in higher structures. The optimum performance of C-LSPSW system was observed when the plastic moment capacity ratio of CBs to HBEs (M-pCB/M-pHBE) was 2.0. As a result, an optimal solution with M-pCB/M-pHBE = 2.0 was suggested as a good compromise between the architectural requirements, material efficiency, and seismic performance.

Abstract ：
In this paper, the dynamic model of an eccentric rotating carbon fiber reinforced polymer (CFRP) laminated cylindrical shell based on the first-order shear deformation theory is established for the first time. The buckling and free vibration analyses of the eccentric rotating CFRP laminated cylindrical shell under the axial excitation are presented. Taking into account the influences of Coriolis force and centrifugal force caused by eccentric rotation. By utilizing the Hamilton principle, the first-order shear deformation theory and the von-Karman type nonlinear geometric relationship, a system of the partial differential governing equations for the eccentric rotating CFRP laminated cylindrical shell is derived. Then, the ordinary differential equations of the eccentric rotating CFRP laminated cylindrical shell are obtained according to Galerkin method. The present method are validated by carrying out some comparisons with the existing results in the published literatures. The natural frequencies and critical buckling loads of the system are solved numerically. In this study, the influences of the eccentric distance, ratio of radius to length, rotating speed as well as the number of layers of the eccentric rotating CFRP laminated cylindrical shell on the buckling and free vibration behaviors are discussed.& nbsp; (c) 2021 Elsevier Inc.

Abstract ：
Stainless steel circular hollow section (CHS) members have been widely used in building structures because of their comparable strength to structural carbon steels, attractive appearance and excellent corrosion resistance. However, research on stainless steel CHS members has been limited to cold-formed members, whereas hot rolled CHS columns have received less attention. To this end, the flexural buckling performance of hot-rolled duplex stainless steel CHS columns was investigated by a comprehensive experimental and numerical programme. A total of seven hot-rolled duplex stainless steel CHS columns covering two cross-sectional sizes with varying lengths have been tested under compression. Based on the test results, finite element (FE) models were developed and used in parametric studies to generate data points with a wider range of geometric dimensions. Comparing the test and FE results with current design guidance, it was found that the Chinese standard, CECS 410, and North American design guidance, AISC DG 27, underestimate significantly the flexural buckling resistance of such columns, while the design method in Eurocode 3: Part 1-4 might be unsafe in predicting the resistances for low slenderness values. New column buckling curves based on the Eurocode 3 and AISC DG 27 design formulae with improved accuracy and reduced scatters were also proposed and validated through careful reliability analysis.

Abstract ：
本文基于2015-2019年中国沪深两市A股上市企业数据,将A股纳入MSCI新兴指数视为一项准自然实验,使用PSM-DID方法进行检验,分析纳入MSCI新兴指数对股价崩盘风险的影响及其作用机制.基准结果表明,纳入MSCI指数加剧了A股企业的股价崩盘风险,该影响主要体现在市值规模较小和分析师关注较低的企业中.机制分析表明,投资者情绪高涨是造成股价崩盘风险的主要渠道;提升企业的信息披露质量会显著降低纳入MSCI新兴指数带来的股价崩盘风险.本文不仅为A股纳入MSCI新兴指数的影响提供了经验证据,也为规范上市公司和维护资本市场稳定提供了有益借鉴.
