Optimized FRP cable arch structure
The invention discloses an optimized FRP cable arch structure. The two ends of an FRP curved arch pipe are connected with a foundation body through arch foot anchoring systems. The FRP curved arch pipe is filled with seawater and sea sand recycled concrete; the FRP prestress inhaul cables are connected between the foundation bodies. The FRP supporting pipes are evenly distributed between the FRP curved arch pipes and the FRP prestress inhaul cables. The FRP supporting pipe is filled with seawater and sea sand recycled concrete; one end of the FRP supporting pipe is connected with the FRP prestress inhaul cable through the inhaul cable connecting system, and the other end of the FRP supporting pipe is connected with the FRP curved arch pipe through the supporting connecting system. By the adoption of the arch foot anchoring system and the supporting and connecting system, connection between brittle and non-weldable components is well achieved, the joint has certain rotating ductility, local stress concentration is relieved, and brittle failure of the joint is relieved or avoided.
本发明公开了一种优化后的FRP索拱结构，FRP曲拱管的两端通过拱脚锚固系统与基础本体连接；FRP曲拱管内部灌装有海水海砂再生混凝土；FRP预应力拉索连接在基础本体之间；FRP支撑管均匀分布在FRP曲拱管和FRP预应力拉索之间；FRP支撑管内部灌装有海水海砂再生混凝土；FRP支撑管一端通过拉索连接系统与FRP预应力拉索连接，另一端通过支撑连接系统与FRP曲拱管连接。本发明通过采用拱脚锚固系统、支撑连接系统较好地解决了各脆性且不可焊接构件之间的连接，并使得节点具有一定的转动延性，缓解了局部应力集中，减轻或避免了节点脆性破坏。
