框架结构中混凝土强度与配筋的关系

结合实际工程的PKPM的电算过程，对框架结构中梁、板、柱各构件选用不同强度等级的混凝土和不同牌号的钢筋分别进行计算。通过将各种构件的计算结果进行对比分析可知，选用高级别的钢筋会明显降低钢筋的用量，同时各种构件的受力性能会随之发生变化。

The Relations of Concrete Strength and Fixture in Framework

According to calculated results of practical engineering, This paper introduces the different results of the project in the PKPM engineering calculation software. In the process of calculation, this article chooses different grades of concrete strength and different grades of steel for the components （the floors,the beams and the pillars） in the process of calculation. And this paper compares and analyzes the calculated results, then determines the reasonable strength of concrete and grade of steel, and analysis the changes of mechanical properties for the components.
