混凝土标号
Examples
- In this thesis , the experimental research of the behavior of high strength concrete axial compression columns and eccentric compression columns under non - uniform temperature field are conducted . from the experimental analysis , the variational regularity of ultimate load capacity and deformation of high strength concrete compression - flexure members under non - uniform temperature field is obtained . the influences of different factors including temperature , stirrup contents , strength grade of concrete , pre - loading level , eccentricity and different loading - temperature paths to refractory capability of members are investigated
文中还对高强混凝土轴心受压柱和偏心受压柱在不均匀温度场下的力学性能进行了试验研究，通过试验分析了高强混凝土压弯构件极限承载力和变形在不均匀温度场下的变化规律，考察了不同升温温度、箍筋用量、混凝土强度等级、预加荷载水平、荷载偏心以及荷载?温度途径等对构件耐火性能的影响，通过试验量测，得到了构件的截面温度场。
