［摘要］我國(guó)現(xiàn)行《建筑抗震鑒定標(biāo)準(zhǔn)》（GB 50023—2009）規(guī)定，混凝土砌塊類房屋的橫墻間距及寬度限值為普通粘土磚房屋的限值乘以相應(yīng)的修正系數(shù)，然而，房屋的橫墻間距及寬度限值與材料強(qiáng)度、樓層重力荷載代表值等參數(shù)之間并非簡(jiǎn)單的線性關(guān)系，故《建筑抗震鑒定標(biāo)準(zhǔn)》（GB 50023—2009）中規(guī)定的算法有一定的不合理性。根據(jù)結(jié)構(gòu)力學(xué)原理，推導(dǎo)出砌塊類房屋橫墻間距及寬度限值的計(jì)算方法，并與規(guī)范算法進(jìn)行對(duì)比分析，提出不同墻體類別及砂漿強(qiáng)度的合理修正系數(shù)。

Abstract:The current code for “Standard for seismic appraisal of buildings” (GB 50023—2009) stipulates that, cross wall spacing and width limit of the horizontal walls of concrete block buildings are the limits of ordinary clay brick houses multiplied by the corresponding correction coefficient. However, there is not a simple linear relationship between cross wall spacing and width limits of the horizontal walls of buildings and the material strength, representative value of the floor gravity load and other parameters. Therefore, the algorithm specified in the “Building seismic appraisal standard” (GB 50023—2009) is unreasonable. According to the principle of structural dynamics, the calculation method of cross wall spacing and width limit of the horizontal wall of the block building was derived, and compared with the standard algorithm, reasonable correction coefficients for different wall types and mortar strength were proposed.

Keywords:block structure; concrete hollow block； cross wall spacing； housing width； load-bearing walls；correction coefficient
