［摘要］比較了我國和美國配筋砌體扶壁柱的設(shè)計(jì)方法、荷載組合和材料強(qiáng)度取值，并考慮工程實(shí)際對(duì)美國材料強(qiáng)度按照我國要求進(jìn)行了轉(zhuǎn)換。針對(duì)具體算例，按美國和我國不同的設(shè)計(jì)表達(dá)式進(jìn)行了配筋砌體扶壁柱的配筋設(shè)計(jì)對(duì)比。算例表明，對(duì)于正截面配筋，美國設(shè)計(jì)結(jié)果比我國設(shè)計(jì)結(jié)果高出40%。對(duì)兩國配筋砌體扶壁柱設(shè)計(jì)結(jié)果差異產(chǎn)生的原因進(jìn)行分析，以對(duì)兩國規(guī)范設(shè)計(jì)要求的差異有進(jìn)一步的理解。［關(guān)鍵詞］砌體結(jié)構(gòu); 扶壁柱; 容許應(yīng)力; 極限狀態(tài)法設(shè)計(jì); 大偏心受壓中圖分類號(hào)：TU365 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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
