迄今计算桥梁的荷载横向分布系数大多采用近似法。如对于窄桥则假设桥面的横向刚度为无穷大、桥面的变形为一直线;而对于阔桥则假设桥面的横向为简支板(刚度为零)。这些计算虽然比较简便,但误差较大,再者对于微弯板的内力计算也无更好的简易方法。对此,本文提出一种《有限纵横条分法》供大家讨论参考。 To date, most of the transverse load distribution coefficients of bridges are calculated by approximate method. For a narrow bridge, for example, the lateral stiffness of the deck is assumed to be infinity and the deformation of the deck is a straight line. For a wide bridge, the deck is assumed to be simply supported (stiffness is zero) laterally. Although these calculations are relatively simple, but the error is larger, in addition to the calculation of the internal force of the micro-bent plate there is no better simple method. In this regard, this paper presents a “limited vertical and horizontal bar” for your discussion and reference.
