［摘要］比较了我国和美国配筋砌体扶壁柱的设计方法、荷载组合和材料强度取值，并考虑工程实际对美国材料强度按照我国要求进行了转换。针对具体算例，按美国和我国不同的设计表达式进行了配筋砌体扶壁柱的配筋设计对比。算例表明，对于正截面配筋，美国设计结果比我国设计结果高出40%。对两国配筋砌体扶壁柱设计结果差异产生的原因进行分析，以对两国规范设计要求的差异有进一步的理解。［关键词］砌体结构; 扶壁柱; 容许应力; 极限状态法设计; 大偏心受压中图分类号：TU365 文献标识码：A 文章编号：1002-848X(2015)17-0067-06
Comparison analysis of reinforced concrete masonry pilaster calculations in China and AmericaMa Bo, Bao Jinlong(Shanghai Nuclear Engineering Research & Design Institute, Shanghai 200233, China)Abstract: The design method, load combination, material strength of reinforced masonry pilaster in China and America were compared, and replacement of American material into Chinese required material according to engineering practice was considered. According to the practical calculation example, comparison of reinforcement design of the masonry pilaster was carried out according to different equations in codes of the two countries. The example comparison indicates that reinforcement design results of normal sections in American code are 40% larger than that of Chinese code. Reasons for result difference of two countries were analyzed to further understand the differences in Chinese and American design codes.Keywords: masonry structure; pilaster; allowable stress; limit state design method; large eccentric compression
