摘要:
以某大跨连续梁桥施工膺架为工程背景,先采用有限元软件对原图纸和荷载方案进行校核,发现其承载能力不足的缺点后,对施工膺架的碗扣支架、贝雷梁、横向支撑梁、钢管立柱进行了设计,并用有限元软件对设计后的施工膺架各个构件进行了强度和稳定性验算.结果表明:在保证造价经济的前提下,设计后的桥梁施工膺架在承载力方面得到很大提高,满足桥梁施工要求.
Abstract:
Taking the construction frame of a long-span continuous girder bridge as the engineering background, the original drawings and load schemes were checked by using finite element software. , horizontal support beams, and steel pipe columns were designed, and the strength and stability of each component of the designed construction frame were checked with finite element software. The results showed that: under the premise of ensuring cost economy, the designed bridge construction frame The bearing capacity has been greatly improved to meet the requirements of bridge construction.
