(接上期)耐候钢梁为减少钢梁的后期养护,可采用耐候钢进行小型桥梁建设。支座、防震设施及其他桥梁支座类型主要有单向活动支座、双向活动支座、固定支座。一联桥梁中,只在一个墩顶上设置固定支座,当同一墩顶支座间距较小,桥梁横向变形较小时,同一墩顶的支座可均采用固定支座,否则只设置一个固定支座,其他支座为单向(横向)活动支座。非固定墩上设置单向 (Continued) Weathering Steel Beams In order to reduce the post-maintenance of steel beams, we can use weathering steels to build small bridges. Supports, anti-vibration facilities and other types of bridge bearings are mainly one-way movable bearing, two-way movable bearing, fixed bearing. In a joint bridge, a fixed bearing is only set on the top of one pier. When the distance between the same bearing is small and the transverse deformation of the bridge is small, the bearings on the same pier may adopt a fixed bearing, otherwise, only one fixed Supports, other bearings for one-way (lateral) activities bearing. Non-fixed pier set one-way
