摘要 ：
钢-混凝土-钢组合墙外部被钢板包围,内部填充混凝土,通过各种连接件或加劲肋将钢板与混凝土连为整体。在传统连接形式的基础上,提出了新型的哑铃型连接件,将其与传统栓钉配合用于组合墙中。设计、制作了4个哑铃型连接件钢-混凝土-钢组合墙试件,通过单调施加竖向均布面荷载来研究其竖向抗压性能。试验结果表明:钢板局部屈曲是试件的破坏形式之一,这不受连接件形式与布置方案的影响;连接件的布置方案决定了钢板临界屈曲应力,连接间距越小则临界屈曲应力越大;试件竖向承载能力达到峰值之后,会较快的下降,即钢板的屈曲后强度下降较快。对试验结果进行分析,参考规范以及相关研究结果,得到了竖向承载力实用计算公式,计算结果与试验数...

摘要 ：
Earthquake action is multi-dimensional and random. The anti-seismic capability of beam-column joints in reinforced concrete (RC) frame structures under arbitrary horizontal direction loading may be lower than the design capability for unidirectional earthquake actions. To date, detailed calculation methods for the shear capability and shearing performance of joints in RC frames under arbitrary horizontal direction loading have not been reported. For this reason, in this work, the shear mechanism of beam-column joints in an RC frame under arbitrary horizontal direction loading is analysed. This study shows that two oblique compression zones form at the corners of the joint when a synthetic shear force is imposed on the joint, and an oblique compression strut is formed in the core area of the joint, which is different from the shear mechanism of a joint under unidirectional loading. Furthermore, a shear capacity calculation model is established based on the strut-and-tie model. The predicted values of the shear capability in this work are in good agreement with the reported experimental results.

摘要 ：
针对支承大跨度屋盖钢管柱的受力特点,进行了3个低轴压比钢管柱在水平往复荷载下的模型试验.采用非线性有限元法对钢管柱的变形性能进行计算分析,分别考察长细比、径厚比和轴压比对钢管柱屈服变形角和极限变形角的影响.试验结果表明:当轴压比为0.2左右时,钢管柱在水平往复荷载作用下,钢管柱的滞回曲线均为饱满的梭形.当径厚比较小时,钢管柱塑性变形发展减缓,损伤程度下降,耗能能力增强;当长细比较小时,钢管柱塑性变形发展加快,耗能能力减弱.钢管柱进入弹塑性阶段后,底部发生环向外凸变形,在达到极限承载力时,柱底外鼓非常显著.屈服变形角和极限变形角均远大于规范限值.有限元分析结果表明:钢管柱的屈服变形角与轴压比、长...

摘要 ：
应国家绿色宜居的规划要求,乡村住宅将由频繁新建向长寿命发展。为此,乡村住宅的耐久性将和城镇住宅一样需要予以重视。温度、湿度等环境因素对结构耐久性影响显著,现有评价方法中上述数据往往基于气象监测获得,目前乡村缺乏相关数据。既有气象研究结果表明:由于城市热岛效应和干岛效应的存在,城乡温度和相对湿度存在一定差别。基于数据调研,总结了典型城市的热岛和干岛强度,并基于规范耐久性评价方法讨论了基于城市住宅耐久性评价方法、城乡温度和湿度差对乡村混凝土住宅碳化与锈蚀评价的可行性。研究结果表明:大部分乡村住宅可按城市建筑进行耐久性评价,热岛和干岛效应较大的地区,可通过考虑城乡温差和湿度差对乡村住宅的耐久性进行评...

摘要 ：
Based on the mechanical features,three tests with different specimens were performed on steel pipe columns with low axial compression ratio,supporting large-span roofs under reversed horizontal loading. The nonlinear finite element method was used to analyze the deformation performance of steel pipe columns,and the effects of slenderness ratio,diameter-thickness ratio,and axial compression ratio on the yield deformation angle and ultimate deformation angle were investigated. The test results show that when the axial compression ratio is about 0.2,the hysteresis curves generated by the steel pipe columns under reversed horizontal loading show a full shuttle shape. When the diameter-thickness ratio is relatively small,the rate of plastic deformation of the steel pipe column is slowed down,the degree of damage is reduced,and the energy dissipation capacity is enhanced. When the slenderness is relatively small,the growth of plastic deformation of the steel pipe column is accelerated and the energy dissipation capacity gets weakened. As the steel pipe column enters the elastoplastic zone(behavior),a ring form of deformation occurs peripherally or externally at the bottom and a drum form of deformation occurs directly at bottom of the column. These deformations significantly affect the ultimate bearing capacity. The yield deformation angle and the ultimate deformation angles are much larger than those mentioned in the specification. The finite element analysis results show that the yield deformation angle has a linear relationship with the axial compression ratio and the slenderness ratio;the slenderness ratio has the maximum influence on the yield deformation angle,the axial compression ratio has some influence when compared to slenderness ratio(second in the order of influence),and the diameter-thickness ratio has minimum influence. When the slenderness ratio is not less than 40,the yield deformation angle can satisfy the required target drift angle of 1/150. The ultimate deformation angle of steel pipe columns has a linear relationship with the axial compression ratio and the slenderness ratio and has a nonlinear relationship with the diameter-thickness ratio;the diameter-thickness ratio has the largest influence on the ultimate deformation capacity of steel pipe columns,the axial compression ratio is the second(has some influence),and the slenderness ratio has the least influence. When the values of axial compression ratio and the diameter-thickness ratio do not exceed 0.2 and 30,respectively,the ultimate deformation angle of steel pipe columns can satisfy the required target drift angle of 1/30. By applying the results of finite element analysis in the calculations,yield deformation angle and ultimate deformation angle of steel pipe columns are obtained,which are used to estimate the deformation capacity of steel pipe columns. © 2021, Editorial Board of Journal of Tianjin University(Science and Technology).

摘要 ：
Stability prediction is a key step to implement a real-time hybrid simulation (RTHS) testing successfully. There are two kinds of stability prediction methods based on continuous and discrete transfer function. In the family of continuous transfer function based methods, the numerical and physical substructures are seen as continuous systems together with loading system. In discrete family, all subsystems in RTHS are regarded as discrete systems. Actually, in a real RTHS, the numerical substructure is discrete; the physical substructure is continuous. Meanwhile, the signal coordination is needed to balance the sampling interval between numerical solution and physical loading, which is ignored in the reported methods. In order to predict the stability of RTHS system more accurately, this work develops a discrete-continuous stability analysis method through the concept of gain margin, which can consider the performance of numerical substructure, physical substructure, loading system and signal coordination comprehensively. And the accuracy of the method is verified by SIMULINK simulation and experimental testing. Based on shaking table and actuator RTHS systems, the performance of continuous and discrete methods is compared with the proposed method analytically. The results show that the discrete method and continuous method have slight influence on the stability prediction with a small integration step (e.g 1 ms). However, with the increase of integration step, compared with the discrete-continuous method, the discrete method and continuous method may overestimate or underestimate the stability of a real RTHS system.

摘要 ：
隔震储罐的抗震性能分析中,底部剪力和隔振层位移是两个重要指标.Housner模型是储罐抗震设计中常用的液体简化模型,其在计算储罐底部剪力时有良好的准确性,并被广泛验证,但是对于隔振层变形的计算效果鲜有研究.运用实时子结构试验方法,对四条地震激励下的不同摩擦系数的摩擦摆隔震储罐进行了试验研究,并通过Housner模型代替试验储罐对各个工况进行了仿真.分析结果表明:地震荷载作用下,Housner模型用于储罐底部剪力计算时准确性较高,与实验结果相比平均误差仅为11％.但是在隔振层滑移位移的计算中与实验结果差距较大,平均误差为22％,最大误差超过30％.
