1、学校代码： 10128学 号： 本科毕业设计外文文献翻译（ 题 目：Shear wall structural design of high-level framework学生姓名： 学 院：土木工程学院系 别：建筑工程系专 业：土木工程专业（建筑工程方向）班 级：土木08-（5）班指导教师： Shear wall structural design of high-level frameworkWu JichengAbstract: In this paper the basic concepts of manpower from the frame shear wall structure

2、, analysis of the structural design of the content of the frame shear wall, including the seismic wall shear span ratio design, and a concrete structure in the most commonly used frame shear wall structure the design of points to note.Keywords: concrete; frame shear wall structure; high-rise buildin

3、gs The wall is a modern high-rise buildings is an important building content, the size of the frame shear wall must comply with building regulations. The principle is that the larger size but the thickness must be smaller geometric features should be presented to the plate, the force is close to cyl

4、indrical. The wall shear wall structure is a flat component. Its exposure to the force along the plane level of the role of shear and moment, must also take into account the vertical pressure. Operate under the combined action of bending moments and axial force and shear force by the cantilever deep

5、 beam under the action of the force level to look into the bottom mounted on the basis of. Shear wall is divided into a whole wall and the associated shear wall in the actual project, a whole wall for example, such as general housing construction in the gable or fish bone structure film walls and sm

6、all openings wall. Coupled Shear walls are connected by the coupling beam shear wall. But because the general coupling beam stiffness is less than the wall stiffness of the limbs, so. Wall limb alone is obvious. The central beam of the inflection point to pay attention to the wall pressure than the

7、limits of the limb axis. Will form a short wide beams, wide column wall limb shear wall openings too large component at both ends with just the domain of variable cross-section rod in the internal forces under the action of many Wall limb inflection point Therefore, the calculations and construction

8、 shouldAccording to approximate the frame structure to consider. The design of shear walls should be based on the characteristics of a variety of wall itself, and different mechanical characteristics and requirements, wall of the internal force distribution and failure modes of specific and comprehe

9、nsive consideration of the design reinforcement and structural measures. Frame shear wall structure design is to consider the structure of the overall analysis for both directions of the horizontal and vertical effects. Obtain the internal force is required in accordance with the bias or partial pul

10、l normal section force calculation. The wall structure of the frame shear wall structural design of the content frame high-rise buildings, in the actual project in the use of the most seismic walls have sufficient quantities to meet the limits of the layer displacement, the location is relatively fl

11、exible. Seismic wall for continuous layout, full-length through. Should be designed to avoid the wall mutations in limb length and alignment is not up and down the hole. The same time. The inside of the hole margins column should not be less than 300mm in order to guarantee the length of the column

12、as the edge of the component and constraint edge components. The bi-directional lateral force resisting structural form of vertical and horizontal wall connected. Each other as the affinity of the shear wall. For one, two seismic frame shear walls, even beam high ratio should not greater than 5 and

13、a height of not less than 400mm. Midline column and beams, wall midline should not be greater than the column width of 1/4, in order to reduce the torsional effect of the seismic action on the column. Otherwise can be taken to strengthen the stirrup ratio in the column to make up. If the shear wall

14、shear span than the big two. Even the beam cross-height ratio greater than 2.5, then the design pressure of the cut should not make a big 0.2. However, if the shear wall shear span ratio of less than two coupling beams span of less than 2.5, then the shear compression ratio is not greater than 0.15.

15、 The other hand, the bottom of the frame shear wall structure to enhance the design should not be less than 200mm and not less than storey 1/16, other parts should not be less than 160mm and not less than storey 1/20. Around the wall of the frame shear wall structure should be set to the beam or dar

16、k beam and the side column to form a border. Horizontal distribution of shear walls can from the shear effect, this design when building higher longer or frame structure reinforcement should be appropriately increased, especially in the sensitive parts of the beam position or temperature, stiffness

17、change is best appropriately increased, then consideration should be given to the wall vertical reinforcement, because it is mainly from the bending effect, and take in some multi-storey shear wall structure reinforced reinforcement rate - like less constrained edge of the component or components re

On the short shear wall high-rise building design J.Keyuan, 2008, (O2).高层框架剪力墙结构设计 摘要: 本文从框架剪力墙结构设计的基本概念人手， 分析了框架剪力墙的构造设计内容， 包括抗震墙、剪跨比等的设计， 并出混凝土结构中最常用的框架剪力墙结构设计的注意要点。关键词:混凝土； 框架剪力墙结构； 高层建筑 剪力墙是现代高层建筑中一项重要建筑内容，框架剪力墙的尺寸大小必须符合建筑规定

19、原则是尺寸较大但厚度必须较小，几何特征应该呈板状，受力接近于柱形。在剪力墙结构中 墙是平面构件其承受力沿着平面作用的水平剪力和弯矩外，还必须考虑到竖向压力。在弯矩和轴力及剪力的共同作用下进行作业，其受力水平作用下可以看成了底部嵌固于基础上的悬臂深梁。在实际工程中剪力墙分为整体墙和联肢墙，整体墙就比方如一般房屋建筑的山墙或者鱼骨式结构片墙和小开洞墙。而联肢墙是由连梁联接起来的剪力墙但是因为一般连梁的刚度要小于墙肢的刚度，所以墙肢单独作用非常明显。连梁中部出现的反弯点要注意墙肢轴的压比限值。当剪力墙开洞过大时便形成宽梁、宽柱所组成的短墙肢，构件形成的两端带有刚域的变截面杆件在内力作用下许多墙肢将出

20、现反弯点，因此，计算和构造应该照近似框架结构来考虑。设计剪力墙时，应该根据各种墙体本身的特点，以及不同的受力特征和要求，墙体内力分布状态和破坏形态 全面具体地考虑设计配筋和构造措施。框架剪力墙结构设计是考虑了水平和竖直两个方向作用所进行的结构整体分析所以求得内力后需按照偏压或偏拉进行正截面受力计算。框架剪力墙的构造设计内容框架墙结构就高层建筑而言，在实际工程中运用最多，抗震墙要有足够的数量以满足层间位移限值，位置相对灵活。抗震墙适合连续布置、全长贯通。在设计时应避免墙肢长度的突变以及洞口上下的不对齐。同时洞边距柱的内侧应不小于300mm 以保证柱作为边缘构件的作用和约束边缘构件的长度。双向抗侧

21、力的结构形式是使纵横墙相连使彼此成为有缘的剪力墙。对于一、二级抗震框架剪力墙，连梁跨高比不宜大于5，且高度不小于400mm。柱中线与梁、墙中线不宜大于柱宽的14，以减少地震作用对柱的扭转效应否则可以采取加强柱内配箍率的方法来弥补。如果剪力墙的剪跨比大干2连梁的跨高比大于25，那么设计的剪压比不宜大干02但如果剪力墙的剪跨比小于2 连梁的跨度小于25，那么剪压比不大于0. 15。另一方面，框架剪力墙结构的底部加强区的设计范围应该不小于200mm且不小于层高的1/16，其他部位应不小于160mm且不小于层高的120框架剪力墙结构的墙周围应设置梁或暗梁与端柱组成边框。剪力墙的水平分布能够起抗剪作用，这种设计中 当建筑物较高较长或为框剪结构时 配筋应该适当增加，特别是在梁部位或温度、刚度变化等敏感部位最好适当增加，这时还应该考虑到墙的竖向钢筋，因为它主要起抗弯作用，并且在一些多层剪力墙构造配筋时所取的配筋率般不扣除约束边缘构件或构件边缘构件的钢筋。参考文献：1恻林荣，何雅明浅议高层建筑短肢剪力墙的设计【J】今日科苑，2008，(O2)
