钢筋混凝土梁是农村房屋的主要承重构件。通过计算,可以确定截面尺寸以及纵向受力钢筋、箍筋和弯起钢筋的数量。但是,实际的结构构件往往要涉及多方面的问题,不可能都反映在计算公式中。因此,人们根据长期的实践经验和试验研究结果,并考虑到施工的可能与方便,将有些内容总结为“构造要求”,以解决那些未能反映在计算 Reinforced concrete beams are the main load-bearing components of rural houses. Through calculations, the size of the section and the number of longitudinally stressed bars, stirrups and bent bars can be determined. However, the actual structural components often involve many problems, which cannot be reflected in the calculation formula. Therefore, based on long-term practical experience and experimental research results, taking into account the possibility and convenience of construction, some of the contents are summarized as “structural requirements” to address those that are not reflected in the calculations.
