寒区系杆拱桥桥面横向温度模式及静力性能
Transverse temperature mode and static performance of the deck of tied arch bridges in cold regions
摘要
Abstract
To investigate the transverse temperature patterns and the static structural behavior of tied arch bridge decks in cold regions,this study analyzed transverse temperature gradients using actual temperature measurements and nearly 50 years of meteorological data.Midas software was employed to develop a mechanical model of the bridge's temperature field,deriving temperature effects under transverse temperature gradients and comparing them with the code for design on reinforced and prestressed concrete structure of railway bridge and culvert in China.The findings indicate that the transverse temperature differences across the tied arch bridge decks exhibit a nonlinear distribution,with greater differences occurring further from the centerline.The temperature gradient pattern is symmetrical about the centerline of the bridge deck,exhibiting a power-exponential distribution within half the range.The 100-year transverse temperature model for the bridge deck in the study area was established,revealing that the stress and displacement of each control section exceed those predicted by the code for design on reinforced and prestressed concrete structure of railway bridge and culvert in China.The research results provide a reference for engineering applications.关键词
