“公路”桥梁的非机动车道的荷载如何计算,请大神指出哪本规范有此说明
我有更好的答案
《城市桥梁设计规范》，建设部（CJJ 11-2011）里面有。
《公路桥涵设计通用规范》JTGD60—2004

出门在外也不愁求大神帮忙翻译一题土木工程专业英语题目!In addition totension and compression, another force is at work, namely shear, which wedefined as the tendency of a material to fracture along the lines of stress.Theshear might occur in a vertical plane, but it also might run along thehorizontal axis of the beam, the neutral plane, where there is neither tensionnor compression.Altogether,three forces can act on a structure: vertical-those horizontal-th and those that act upon it with a rotating or turningmotion. Forces that act at an angle are a combination of horizontal andvertical forces. Since the structures designed by civil engineers are intendedto be stationary or stable, these forces must be kept in balance.The verticalforces, for example, must be equal to each other. If a beam supports a loadabove, the beam itself must have sufficient strength to counterbalance thatweight.The horizontal forces must also equal each other so that there is nottoo much thrust either to the right or to the left. And forces that might pullthe structure around must be countered with forces that pull in the opposite direction.

此外totension和压缩,另一种力量在工作,即剪切,其定义为材料沿应力线断裂的倾向.力可能在垂直平面内发生,但也可能沿着梁的水平轴,中性面,那里既不是完全,tensionnor压缩.三力可以作用在结构：垂直的那些行为或下来；那些行为水平侧；和那些对它做一个旋转或turningmotion.作用在一个角是一个组合的横向和垂向力的力量.由于土木工程师设计的结构为固定或稳定,这些部队必须保持平衡.例如,verticalforces,必须相等.如果一个梁支撑loadabove,梁本身必须具有足够的强度,以抵消thatweight.水平力也必须相等,有不多的推力要么向右或向左.和军队可能扣结构必须与力量,在相反的方向拉反击.
