Small cross-sections of boundary elements easily induce the “internal tension” phenomenon of steel plate shear walls, making it difficult to fully utilize the seismic performance of buckling-restrained steel plate shear walls. The design of cross-sections of boundary elements is related to their internal force requirements, and analyzing the internal force requirements of boundary columns is meaningful. Based on the proposed buckling-restrained steel plate shear wall with multi-concrete panels (MBRSPSW), the analytical expressions for the internal force of the boundary column of the MBRSPSW were theoretically derived in this paper. Combined with the experimental research on the buckling-restrained steel plate shear wall horizontally assembled multi-concrete panels (H-MBRSPSW), its numerical model was established and verified. The internal force distributions of the boundary column obtained from numerical analysis and analytical calculation were further compared. The research results indicate that the inner steel plates in the MBRSPSW are divided into constrained regions and unconstrained regions. The axial force, shear force, and bending moment distributions of the boundary column from the analytical calculation results agree with those from the numerical analysis results, and the internal force calculation expressions of the boundary column are correct. The research results can provide a reference for the design of this category of steel plate shear walls.

过小的边缘构件截面易出现钢板剪力墙的内拉现象,难以充分发挥防屈曲钢板剪力墙的抗震性能,边缘构件截面设计与其内力需求相关,分析边缘柱的内力需求显得尤为必要。基于提出的带多块混凝土板的防屈曲钢板剪力墙,本文理论推导了带多块混凝土板的防屈曲钢板剪力墙边缘柱内力的解析计算表达式,结合已开展的带多块水平拼装的混凝土板的防屈曲钢板剪力墙试验研究,建立并验证了其数值模型,进一步对比了数值分析和解析计算得到的边缘柱的内力分布情况。研究结果表明,带多块混凝土板的防屈曲钢板剪力墙的内藏钢板划分为约束区域和非约束区域。边缘柱的轴力、剪力及弯矩分布的解析计算结果与数值分析结果较为接近,边缘柱的内力计算表达式正确。研究成果可为该类钢板剪力墙的设计提供参考。

过小的边缘构件截面易出现钢板剪力墙的内拉现象,难以充分发挥防屈曲钢板剪力墙的抗震性能,边缘构件截面设计与其内力需求相关,分析边缘柱的内力需求显得尤为必要。基于提出的带多块混凝土板的防屈曲钢板剪力墙,本文理论推导了带多块混凝土板的防屈曲钢板剪力墙边缘柱内力的解析计算表达式,结合已开展的带多块水平拼装的混凝土板的防屈曲钢板剪力墙试验研究,建立并验证了其数值模型,进一步对比了数值分析和解析计算得到的边缘柱的内力分布情况。研究结果表明,带多块混凝土板的防屈曲钢板剪力墙的内藏钢板划分为约束区域和非约束区域。边缘柱的轴力、剪力及弯矩分布的解析计算结果与数值分析结果较为接近,边缘柱的内力计算表达式正确。研究成果可为该类钢板剪力墙的设计提供参考。

Small cross-sections of boundary elements easily induce the “internal tension” phenomenon of steel plate shear walls, making it difficult to fully utilize the seismic performance of buckling-restrained steel plate shear walls. The design of cross-sections of boundary elements is related to their internal force requirements, and analyzing the internal force requirements of boundary columns is meaningful. Based on the proposed buckling-restrained steel plate shear wall with multi-concrete panels (MBRSPSW), the analytical expressions for the internal force of the boundary column of the MBRSPSW were theoretically derived in this paper. Combined with the experimental research on the buckling-restrained steel plate shear wall horizontally assembled multi-concrete panels (H-MBRSPSW), its numerical model was established and verified. The internal force distributions of the boundary column obtained from numerical analysis and analytical calculation were further compared. The research results indicate that the inner steel plates in the MBRSPSW are divided into constrained regions and unconstrained regions. The axial force, shear force, and bending moment distributions of the boundary column from the analytical calculation results agree with those from the numerical analysis results, and the internal force calculation expressions of the boundary column are correct. The research results can provide a reference for the design of this category of steel plate shear walls.

在水平荷载作用下,钢板剪力墙易发生屈曲而以拉力带形式提供承载能力及抗侧刚度,其滞回曲线存在捏缩特性[1]。为此,学者提出在钢板两侧拼装约束盖板,以防止内藏钢板发生面外屈曲,即形成了防屈曲钢板剪力墙。
针对防屈曲钢板剪力墙已开展大量研究。范重等[2]研究了螺栓与混凝土盖板的简化计算方法,建立了钢板与盖板相互作用计算模型。马张永等[3]针对半刚性框架-密肋防屈曲钢板剪力墙开展了振动台试验研究及数值分析。田炜烽等[4]推导了考虑墙板抗压能力的钢板剪力墙的刚度、承载力和屈服位移的计算式,并提出了一种通用拉杆模型。谭继可等[5]针对方钢管混凝土框架-冷弯薄壁型钢屈曲约束钢板剪力墙开展了抗震性能试验研究,分析了破坏形态、荷载-位移滞回曲线、耗能能力等抗震性能。周绪红等[6]研究了不同冷弯薄壁型钢屈曲约束形式的钢板剪力墙的往复剪切性能。侯健等[7,8]针对防屈曲钢板剪力墙开展了平面外工作机理与设计方法研究,给出了面外相互作用荷载的理论计算公式。综上可以发现,传统的防屈曲钢板剪力墙主要在内藏钢板两侧外挂单块约束盖板,其尺寸较大,制作运输易产生裂缝,对运输及吊装设备要求很高。为此,文献[910]提出了多块混凝土板拼装的防屈曲钢板剪力墙,对其开展试验研究及有限元分析。随后,钟恒等[11]亦针对设置分块盖板的防屈曲钢板剪力墙开展了抗震性能试验研究及数值分析,结果表明,设置分块盖板的防屈曲钢板剪力墙具有良好的滞回性能,相比盖板不分块的防屈曲钢板剪力墙,设置分块盖板的剪力墙承载力和耗能能力略有降低,但墙体的延性得到提高。范重等[12]采用ABAQUS软件对分块盖板屈曲约束钢板剪力墙的受力机理进行了研究,并建立了简化计算模型。
过去的研究发现,过小的边缘构件截面不足以抵抗内藏钢板形成的屈服荷载,试件出现了内拉变形现象[13]。钢板剪力墙规范[14]给出了非加劲钢板剪力墙边缘框架柱的最小截面惯性矩,以指导确定边缘柱的截面尺寸。范重等[15]研究了边框刚度对屈曲约束钢板剪力墙性能的影响,但未给出量化的边框内力的计算公式。可见,现有研究鲜有针对带分块约束盖板的防屈曲钢板剪力墙的边缘框架构件内力需求的分析。因此,针对带多块混凝土板的防屈曲钢板剪力墙,研究内藏钢板对边缘框架构件附加的内力显得尤为必要。
为此,本文采用理论分析与数值模拟方法,推导了带多块混凝土板的防屈曲钢板剪力墙边缘柱内力的解析计算表达式,结合有限元软件开展数值分析,将解析计算结果与数值分析结果进行对比,有效验证了给出的解析计算表达式的正确性。研究成果可为该类钢板剪力墙的设计提供参考。
图1(a)为带多块混凝土板拼装的防屈曲钢板剪力墙系统(MBRSPSW),主要由水平边缘构件(边缘框架梁)、竖向边缘构件(边缘框架柱)、内藏钢板、混凝土板和螺栓组成。内藏钢板通过鱼尾板采用焊接或栓接方式与边缘构件连接,内藏钢板通过螺栓在其两侧外挂多块混凝土板。混凝土板之间以及混凝土板与边缘构件预留缝隙,以防止其相互挤压造成混凝土压碎。外挂混凝土板不承担主框架的水平和竖向荷载,仅用于约束内藏钢板面外变形,防止内藏钢板屈曲失稳。根据混凝土板的拼装方式,可以分成带多块水平拼装的混凝土板的防屈曲钢板剪力墙(H-MBRSPSW)和带多块竖向拼装的混凝土板的防屈曲钢板剪力墙(V-MBRSPSW)。韩启浩等[9]针对带多块混凝土板的防屈曲钢板剪力墙开展了拟静力加载试验研究,分析了其抗震性能,如图1(b)所示。
内藏钢板的受力变形行为会对边缘框架柱产生附加内力,为定量分析这种不利影响,采用理论方法推导内藏钢板附加给边缘框架柱内力的解析计算表达式。以下分析假定边缘框架梁柱为铰接连接,忽略边缘构件对抗侧力的贡献。
图2给出了带两块水平拼装的混凝土板的防屈曲钢板剪力墙尺寸构造,其中,混凝土板与边缘构件的缝隙为Δ,混凝土板之间的缝隙为δ
在侧向荷载作用下,根据其约束状态,内藏钢板可以划分为两类区域,即带混凝土板(约束盖板)的约束区域和不带混凝土板的非约束区域,其中,约束区域为纯剪切应力状态,非约束区域为斜拉应力状态。内藏钢板的应力状态如图3所示。根据薄板弹性理论[16],屈曲剪切应力(极限剪切应力)τcr可由式(1)确定,k为弹性屈曲系数。针对非约束区域的内藏钢板,周围具有混凝土盖板,可以近似视为四边简支的钢板,其屈曲剪切应力τcr可能低于屈服剪切应力τs,从而发生面外屈曲行为。
式中Es为钢板弹性模量,μ为泊松比,t为钢板厚度,b为钢板的宽度。
混凝土板约束区域I的内藏钢板处于纯剪切应力状态,由平面应力状态的莫尔圆理论,沿着斜柱方向的剪应力为τsc,与之正交方向的正应力为σsc,分别由式(2,3)确定。
式中θr为主应力夹角。
根据von Mises屈服准则[17],引起钢板屈服的对角拉伸应力为σty(实际为第一主应力),可根据式(4)求得。其中,对混凝土板之间的缝隙,即区域II,表示为gσty;对δ缝隙,表示为bσty
式中σy为单轴屈服应力,α为拉力场倾角,可根据规范[14]公式求得,对Δ缝隙,αb=tan-1Δ/l);对δ缝隙,αg=tan-1δ/l)。
非约束区域II的内藏钢板在加载后期会形成拉力场,在混凝土板之间的缝隙区域II,假设沿着斜柱方向的剪应力为gτα,与之正交方向的正应力为gσα,可根据斜截面应力计算公式确定。类似地,在混凝土板与周边构件缝隙区域,即图3中的区域III,可得到相应的斜截面剪应力bτα和正应力bσα的计算表达式。
边缘框架柱内力与内藏钢板相关,根据已有试验研究及数值分析成果,并结合内藏钢板的应力分布状态及构造,柱内力可以分成5区段进行计算,3个与钢板拉力带对应的区段(拉伸区域)和2个钢板纯剪切应力状态对应的区段,如图4(a)所示,截面内力的正方向如图4(b)所示。
对左柱顶部和顶梁左端交点进行受力分析可知,根据力矩平衡原理,对顶梁右端求力矩可得顶梁左端竖向力Vlb1的计算表达式,具体见式(5)。左柱顶水平剪力Hlc1可以通过力矩平衡求得,即对图中左柱底部点A求矩,即可确定左柱顶水平力Hlc1的计算表达式,具体见式(6)
取左柱计算截面与柱顶端为隔离体,通过静力平衡,采用分段函数表示方法,左柱轴力Nlc计算见式(7),框架柱倾角θα=sin-1dh/hw)。为便于基于柱高度绘制内力图形,假定x为计算截面至柱底点A的距离(柱轴方向)。

选取已经完成的试验研究,采用ABAQUS有限元软件建立相应的数值模型,通过将数值分析结果与试验结果进行对比,验证数值模型的正确性。进一步,提取边缘柱数值分析结果,并与解析计算结果进行对比,以验证解析计算表达式的正确性。
为验证本文数值建模方法的正确性,选取钟恒等[11]完成的分块盖板屈曲约束钢板剪力墙进行对比,试件编号为BRSPSW-H。如图5所示,边缘框架梁柱构件为铰接连接,内藏钢板为试件的唯一抗侧力构件,厚度为1.8 mm,内藏钢板两侧均外挂两块水平拼装的约束钢盖板,盖板厚度为30 mm,其余设计参数参见文献[11]。
试验模型中,边缘钢框架采用铰接连接,边缘框架和约束盖板在加载过程中受力较小,其本构关系对数值分析结果影响较小,属于次要构件,采用双线性随动硬化模型来模拟钢材的力学行为,如图6(a)所示,其中屈服强度设置为345 MPa,弹性模量为2.06×105 N/mm2,硬化模量为弹性模量的1%。内藏钢板为模型的主要受力部件,其本构参数对结果影响较大,内藏钢板的材料本构参数可根据试验研究中的材料试验结果确定,采用多折线等向强化本构模型进行模拟,如图6(b)所示。
图7所示,内藏钢板采用四节点减缩积分壳单元(S4R)进行模拟,边缘框架构件采用三维梁单元(B31)进行模拟,约束钢盖板采用八节点减缩积分实体单元(C3D8R)进行模拟。试件中,约束钢盖板与内藏钢板通过螺栓进行连接,由于螺栓的应力与变形行为不是本文的研究重点,采用带连接(LINK)行为的连接器单元(CONN3D2)模拟螺栓连接,可以反映两节点铰接连接及间距不变的特性。内藏钢板与边缘构件通过绑定(tie)连接实现两者的焊接效果。钢盖板与内藏钢板接触面设置接触行为,剪切方向为无摩擦接触,法方向为硬接触(hard contact)。
根据试验条件设定模型边界条件,边缘梁与柱为铰接连接,约束顶梁的面外自由度,以模拟构件的平面内加载行为。底部梁柱铰接点为固定铰支座,放松绕垂直于纸面轴的转动自由度(RZ),其余自由度受约束。通过屈曲分析来考虑钢板的初始缺陷,根据文献可知,试验中钢板的面外变形为2 mm,即取缺陷幅值为2 mm。
图8给出了试验和数值分析得到的内藏钢板平面外变形图,可以看出,拉力带分布均匀、细密,数值分析得到的内藏钢板的面外屈曲变形模式与试验结果吻合良好。数值分析得到的侧向荷载-位移角关系与试验结果的对比如图9所示,可以发现,数值分析得到的滞回曲线和骨架曲线与试验结果吻合较好,数值分析和试验得到的承载能力和加载/卸载刚度较为接近,说明建立的数值模型可以较好地模拟带多块约束盖板的防屈曲钢板剪力墙的力学行为。其中,数值分析和试验得到的最大侧向荷载分别为610.0 kN(-623.7 kN,负向加载)和608.3 kN(-601.5 kN),正负向最大误差为3.69%;正向加载下,数值分析和试验得到的弹性抗侧刚度(即第一级加载时的侧向荷载与侧向位移之比)分别为112.6 kN/mm和112.7 kN/mm,误差很小。以上分析有效验证了数值模型的合理性和正确性,可用于进一步分析各部件的内力分布情况。
根据试验模型的尺寸参数及材料试验结果,将相关数据代入第3.2节,可得边缘框架柱的内力具体计算表达式。当模型加载至位移角为1/250 rad、1/100 rad和1/50 rad时,左边缘框架柱的内力数值分析结果和解析计算结果如图10所示。
图10(a)可见,当模型加载至位移角为1/250 rad和1/50 rad时,边缘框架柱轴力的解析计算和数值分析结果吻合较好,说明给出的轴力计算表达式可以反映框架柱的轴力分布情况。由图10(b)可以发现,边缘框架柱剪力分布的解析计算和数值分析总体吻合较好,但在较小位移角下,如图中位移角为1/250 rad时,两者存在较大差别,主要原因是在较小加载位移角下,内藏钢板的应力状态与假定不完全相符,如加载前期,非约束区域II&III对应的钢板并不一定会发生面外屈曲,内藏钢板形成的正应力影响框架柱剪力分布,最终造成剪力计算有差别。但在较大位移角下,框架柱剪力的解析计算和数值分析结果较为接近,说明给出的剪力计算表达式可以反映框架柱的剪力分布情况。由图10(c)可知,边缘框架柱弯矩分布的解析计算和数值分析吻合较好。如当加载至1/250 rad,1/100 rad和1/50 rad时,由解析计算得到的柱中部弯矩值分别为11490 kN•mm,22435 kN•mm,24977 kN•mm,数值分析得到的柱中部弯矩值分别为10617 kN•mm,21718 kN•mm,24505 kN•mm,两者最大误差为8.2%。综上,边缘框架柱的轴力、剪力及弯矩的解析计算结果与数值分析结果较为接近,证明给出的内力计算表达式的正确性。
(1)带多块混凝土板的防屈曲钢板剪力墙的内藏钢板的应力状态可划分为带混凝土板的约束区域和不带混凝土板的非约束区域。约束区域为纯剪切应力状态,非约束区域为斜拉应力状态,分别给出了对应区域剪应力和正应力的计算表达式。
(2)柱内力划分为多区段进行计算,采用理论分析方法,确定了边缘框架柱的轴力、剪力及弯矩的解析计算表达式。
(3)与试验研究结果进行对比,验证了带多块混凝土板的防屈曲钢板剪力墙的数值模型的合理性和正确性。边缘框架柱的轴力、剪力及弯矩的解析计算结果与数值分析结果较为接近,说明确立的边缘柱内力的解析计算表达式正确。研究成果可为该类钢板剪力墙的设计提供理论参考。
