| 1. | The ratio of span - height of an ordinary tie beam is always less 2 . 5 , so the resisting shear is difficult to achieve 由于一般连梁跨高比小于2 . 5 ,使得受剪承载力很难满足。 |
| 2. | Inclined stirrups are not effective in beams resisting shear reversals , such as seismic loads , because the reversals will cause cracking parallel to the inclined reinforcement , rendering it ineffective 也就是说,哪怕纵向钢筋不弯起(保证支座丛筋在上下都足以抵抗地震力产生的弯矩) ,箍筋用斜的,也不行! |
| 3. | The progress on the relevant research in home and abroad is systematically reviewed firstly . summarizing the research results on theory and test , and made draw conclusions from them . and introduce the main theory of resisting shear 首先,系统回顾了国内外研究进展,就关于抗剪机理的试验研究成果和理论研究成果进行总结,得出几点重要结论,并简要地介绍了现有的主要抗剪理论。 |
| 4. | The formulas to the moment of resistance on the action of the pure moment and to the resisting shear considering the contribution of the concrete haunch on the action of the pure shear are then given . the method to the capacity at the mutual action of moment and shear is analyzed emphatically 在计算抗弯承载力时,不计板托作用,计算截面抗剪承载力时,不计混凝土部分的抗剪作用,这些简化对于有托尤其是深托组合梁是保守的。 |
| 5. | Since the common loads had little effects to the relative displacement of top floor in cshbb , so it was unnecessary to considering them in normal use ultimate state . thermal effects had no influence to the resist compression bearing capacity and resist shear bearing capacity , but had great 温度作用对砌体结构的抗压和抗剪承载能力没有影响,但对砌体结构的顶层山墙和外纵墙的弯曲抗拉承载能力起控制作用,需要考虑温度作用和荷载的组合问题。 |
| 6. | This thesis fetches cold - formed thin - walled c steel beam - to - column connections with self - drilling screw connecting for being researched object in cold - formed thin - walled light steel structure system , have done the following three parts of research work to the performance of beam - to - column connection : ( 1 ) the resisting shear strength experiments of 20 pieces of jointing connected by self - drilling screws 本文取冷弯薄壁轻钢龙骨住宅钢结构中用自攻螺钉连接的c型钢梁柱节点为研究对象,对节点的连接性能作了如下三部分研究工作: ( 1 ) 20个自攻螺钉连接试件的抗剪承载力试验。 |
| 7. | The creative results are as follows : ( 1 ) behavior of the stirrup legs in the loading direction in the joint core ( along the loading direction for circular stirrups ) is different from that perpendicular to the loading direction . the stirrup legs in the loading direction acts as the tension chords in the truss model to resist shear , in the meantime , they confine the compressed diagonal strut from lateral expam - sion 沿受力方向箍肢(或部位)既作为桁架机构的拉杆参与抗剪又对斜压杆受压后沿受力平面侧向膨胀的水平分量起约束作用;垂直受力方向箍肢(或部位)原则上仅对斜压杆沿垂直受力方向侧向膨胀起约束作用。 |
