箍筋

Longitudinal reinforcement has been modeled with discrete element and stirrup has been modeled with smeared element. Smeared element, stirrup has been modeled using membrane element in or on concrete isoperimetric element. The constitutive relationship and failure criterion for concrete is the inter-facial model.

在建立钢筋混凝土的有限元模型时，混凝土采用的单元为八节点六面体等参单元，钢筋单元分为两种情况，纵向钢筋采用分离式钢筋单元，箍筋采用埋藏式钢筋单元，即箍筋作为附着在混凝土等参数单元内或单元上的"膜单元"。

为了解决混凝土砌块砌体剪力墙端部约束区配箍不足的问题，创新研制了在砌块壁内配置箍筋的新型内置箍筋混凝土砌块，并进行了6个内置箍筋的新型砌块砌体试件和2个对比试件的轴心受压试验，充分了解了内置箍筋砌块砌体的受压性能。

This manner can form continuous arrangement effect of hoop bar with less space, and be fit for concrete restricted by stirrup. It also can reduce the concrete crack arised by retortion in the region of frame column, and improve the ductility capability under the earthquake. The construction quality of frame column is improved simultaneously.

该布置方式形成连续且间距较小的箍筋布置效果，有利于发挥箍筋对混凝土的约束作用，减小各种因素可能引起框架柱扭转而在柱非加密区产生的裂缝，改善柱中部区域在地震作用下的延性性能，同时可以提高框架柱的施工质量。

The most common form of web reinforcement used is the vertical stirrup.

最常见的形式箍筋采用的是垂直箍筋。

According to the test of the shear beams reinforced with the stirrup of HRB400 steel bars, the mechanical property of stirrup in the members is studied.

In this thesis, the influence of column force, joint hoop reinforcement, and repeat load on the stress and sheer bearing capability of inclined pressure bar is analyzed utilizing finite element software. In the case study, the column axial force's influence on the inclined pressure bar's equivalent width, stress and sheer bearing capability of RCFEN is obtained by changing the column force when modeling the RCFEN with ANSYS. In the former model, the joint hoop reinforcement influence on the equivalent width inclined pressure bar and the strength of RCFEN is achieved by changing the quantity of joint hoop reinforcement; the inclined pressure bar's equivalent width and the strength variation of RCFEN under cyclic load are gained by applying low frequency cyclic load on the inflection point of column and the middle of beam.

针对上述算例中的框架外节点采用ANSYS进行建模，运用有限元软件分析了柱轴力、节点箍筋、反复荷载对外节点斜压杆承载力、抗剪承载力的影响：改变柱轴力，研究了柱轴力对斜压杆的等效宽度、框架外节点斜压杆承载力、框架外节点斜压杆抗剪承载力的影响；在上述模型中，改变节点箍筋的数量，分析了节点箍筋对斜压杆的等效宽度、框架外节点强度的影响；在上述模型中，在柱反弯点和梁中点均进行低周反复加载，讨论了在反复荷载作用下，框架外节点的斜压杆的等效宽度、框架外节点强度的变化情况。

Times the stirrups; Seismic requirements for the structure, not less than 10 times the diameter of the

箍筋弯后的平直部分长度：对一般结构，不宜小于箍筋直径的5倍；对有抗震等要求的结构，不应小于箍筋直径的10倍。

So its stability is analyzed with ANSYS, considering the promoting effect of stirrups on strength of core concrete.

高墩中通常配置较多的主筋及箍筋，核心混凝土受到箍筋约束，其强度及延性都有所增长，因此对这部分混凝土不能按照规范给出的普通混凝土的应力—应变关系进行分析，必须为它们选用合适的本构关系，才能使分析结果较接近实际值。

Stirrup bend the straight part of the general structure : length, diameter of not less than five times the stirrups; Seismic requirements for the structure, not less than 10 times the diameter of the stirrup.

箍筋弯后的平直部分长度：对一般结构，不宜小于箍筋直径的5倍；对有抗震等要求的结构，不应小于箍筋直径的10倍。

Only the protective concrete cover in the area had spalled off. The concrete confined inside the 5-spirals had generally remained in good condition.

另一方面，五螺箍RC柱於塑铰区发挥良好之韧性，五螺箍所围束之混凝土大致保持完好，混凝土保护层并无严重剥落之情形，且主筋亦无明显的挫屈现象，箍筋亦未发生断裂。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
