箍

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"。

Type YZF duck-billed valve, also be called "rubber flexible check-valve", it has function similar to tide gate, flapper gate but its working principle and structure is different, its mounting pattern is generally classed to pipe hoop form and flange form( flange form is generally used in case that latus rectum is larger than DN800, otherwise pipe hoop form is used).

YZF 型鸭嘴阀，又称"橡胶柔性止回阀"，与潮门，拍门功用相似，但工作原理和结构不同，其安装形式一般分为管箍式和法兰式（法兰式一般大于通径 DN800，管箍式一般小于通径 DN800），本体材质为橡胶，可广泛用于排水管出口，防止水流倒灌，造成事故。

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。

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。
