摘要
给出两组计算平房仓基础底面积的计算公式,分析按老规范进行偏心基础设计中因偏心距取值不当而出现的问题,同时根据新规范,以基础底面积最小为优化目标,针对影响基础偏心距的一些因素,分析在不同条件下基础偏心距对基础可靠度和经济性的影响,从而确定基础偏心距的合理取值.
Two groups of equations, which were used to calculate the foundation area of single-story granary, were given in this paper. Some problems were analyzed because of some unreasonable values of eccentric distance that was adopted in old version code for a eccentric foundation design. Meanwhile, on the basic of new version code, taking minimum foundation area as optimized goal, considering some influence factors of foundation's eccentric distance, the effect of foundation's eccentric distance on the reliability and economy of foundation were analyzed .The reasonable values of foundation's eccentric distance were confirmed.
