improvement factor of part compressive strength

It has been discussed that the value of improvement factor of part compressive strength,design value of compressive strength in part compressive strength calculation of masonry structure and the antiknock bearing capacity proven of the reinforced brick masonry;and some corresponding suggestions are presented.

就砌体结构局部受压计算中局部抗压强度提高系数、抗压强度设计值的取值及配筋砖砌体构件的截面抗震承载力验算等问题进行了分析,并提出了相应的建议,可供设计时参考。

Experimental results show that the strength grades of RPC have a little influence on local compression enhancement coefficient and the coefficient increases with the increase of the local compressio.

试验结果表明:RPC强度等级对局压强度提高系数影响较小;局压强度提高系数随局压面积比的增大而增大;在局压面积比相同时,RPC局压强度提高系数较高强混凝土低。

The calculated values of critical load is much lower than local compressed strength.
