| Abstract: | In order to acquire the spatial stress distribution of the pier-beam fixed joint, a pier-beam fixed joint finite element space model is established and analyzed in different loading cases. The local stress distribution of the pier-beam fixed joint is analyzed in three loading cases, as a result of which the safety and rationality of the design are verified, and the measure for meliorating stress of the pier-beam fixed joint is proposed, with a rational basis provided for future design and construction. |
| Keywords: | continuous rigid frame pier-beam fixed joint local stress finite element |
