摘要
规范规定了混凝土结构设计中,框架梁端混凝土受压区高度,但在施工图设计中,受压区高的限制由于不直观很少验算,容易成为结构设计的盲点,常常出现不满足规范的情况,违反强制性条文。通过对规范条文的分析研究,得出了为了满足规范关于混凝土受压区高度的要求,梁端截面底面与顶面纵向钢筋的配筋量的比值,随着梁端受拉钢筋的配筋率的变化而要求不同,从而使结构设计与审图人员能够直观地判断受压区高度是否超限,此方法有很强的实用性。
Norms in design of concrete structure, ratio of effective height and depth of compression zone of concrete flame beam end, But in the construction design, While the compression zone high due to the limitations of not intuitive rarely checking, Easy to become the structure design of the blind spot, the case that do not meet the standard is often occur. The text based on the analysis of codes, In order to meet the specifications on the height of compressive region concrete requirements, The beam end section bottom surface and the top surface of longitudinal reinforcement ratio of reinforcement, As the beam end tension steel reinforcement ratio changes in the requirements of different. So that the design and the structure of personnel to determine the height of compression zone and intuitive is overrun, This method has very strong practicability.
