1.引言混凝土研究传统的方法以纯现象学为基础。为了得到混凝土的某些参数,往往需要经过设计,进行一系列的试验,而对于所观察到的性能,只是凭丰富的想象而建立起来的假设来给以解释。这样对于很多的理论研究,往往非常难以深入。在高效率的电子计算机和必要的计算机程序进入了结构分析领域以及数值方法的应用,为理论研究提供了特别有力的工具。 1. Introduction The traditional method of concrete research is based on pure phenomenology. In order to obtain certain parameters of concrete, it is often necessary to design and carry out a series of tests, and to interpret the observed performance only on the assumption of rich imagination. This is a lot of theoretical research, often very difficult to in-depth. The application of high-efficiency electronic computers and necessary computer programs into the field of structural analysis and numerical methods has provided a particularly powerful tool for theoretical research.
