近20多年来,南京工学院建筑结构研究室和结构力学研究室在钢筋混凝土和预应力混凝土基本理论方面进行了一系列试验研究和理论分析工作,试验过的试件约1000个,取得了一些成果.这主要反映在以下四个方面.即构件刚度和裂缝研究方面、构件强度研究方面,有关结构抗震研究方面和有限无法计算方面.下面将分别进行必要的介绍,但重点放在刚度和裂缝研究方面.在这一课题研究中,我们提出了一个较完整的计算体系.
In the past 20 years, the Institute of Building Structures and Structural Mechanics of the Nanjing Institute of Technology have conducted a series of experimental researches and theoretical analysis on the basic theories of reinforced concrete and prestressed concrete. About 1,000 specimens have been tested and some have been obtained. Results. This is mainly reflected in the following four aspects: component rigidity and crack research, component strength studies, structural anti-seismic research, and limited computational aspects. The following sections will provide necessary introductions, but focus on stiffness and cracks. Research. In this research project, we proposed a more complete calculation system.
