“双向钢筋混凝土板的内力塑性重分段”一文发表後有陈叔陶及朱可善两位同志的讨论,并有来信询问此方法应用上的一些问题。今就各位同志所提的意见及问题答復如下。 1)苏联结构学派的特点是简化计算方法,同时考虑到施工和使用时结构的实际情况,并使结构的用料经济、施工方便、劳动力节省,在双向钢筋混凝土板的计算方法上,苏联格娃斯捷夫教授假定斜塑性铰线与板边(矩形板)的交角为45°,并假定纵横钢筋比与长短边比的关系而使双向钢筋混凝土板的计算简化是有重大价值的,是苏联结构学派的很好例子,是我们学习的榜样,这就是本文介绍此方法之目的。本文虽引用乔汉生教授的一些理论来证明格娃斯捷夫教授计算双向钢筋混凝土板的基本公式,并在文中注明其来源,但不是本文介绍的重点。
After the publication of the article “Principal plasticity of two-way reinforced concrete slabs”, there were discussions between Chen Shutao and Zhu Keshan, and there were letters asking questions about the application of this method. The replies to the opinions and questions posed by the comrades today are as follows. 1) The structural school of the Soviet Union is characterized by simplified calculation methods, taking into account the actual conditions of the construction and use of the structure, and making the economics of construction materials, construction convenient, and labor savings. In the calculation method of two-way reinforced concrete slabs, the Soviet Union Prof Vastef assumes that the angle between the oblique plastic hinge line and the edge (rectangular plate) is 45°, and assumes that the aspect ratio of the longitudinal and lateral reinforcements is proportional to the ratio of length to length. This makes the computational simplification of the bi-directional reinforced concrete slab of great value. It is the Soviet Union. A good example of a structural school is an example of our study. This is the purpose of this article. Although this article quotes some of the theories of Professor Qiao Hansheng to prove that Gevatsteeff’s calculation of the basic formula of two-way reinforced concrete slabs, and its source in the text, but not the focus of this article.
