目前,公路装配式钢筋混凝土简支梁桥上部构造的主梁比较常用的是“T”形截面。作者根据“偏心受压”法公式 K=1/n±(ca_x)/(Σa~2),配合基本组合型式及各种活载(汽—8、10、13、18、拖—30、60、80、人群)的最不利情况,制成图表,可供设计中查用及采用多种计算方法比较横向分配系数时的校核与分析、研究每根梁肋横向分配系数时的参考。该表特点:使用简便,数据可直接查用,无须再作插入计 At present, the main girder constructed on the upper part of the highway-assembled reinforced concrete simply supported beam bridge is commonly used as a “T” shaped section. According to the formula “Eccentric compression” K = 1 / n ± (ca_x) / (Σa ~ 2), with the basic combination type and various live load (steam -8,10,13,18, drag -30,60 , 80, crowd), make charts to check and analyze the transverse distribution coefficient by using a variety of calculation methods, and to study the reference of each beam rib transverse distribution coefficient. The table features: easy to use, the data can be directly checked, no longer need to insert meter
