High-strength steel pipe ultra-high performance concrete simply support and continuous trussed beam and construction method thereof
The invention relates to a high-strength steel pipe ultra-high performance concrete simply supported and continuous trussed beam which comprises a high-strength steel pipe trussed beam formed by fixing a pressed chord member, a web member and a pulled chord member, the pressed chord member and the pulled chord member are filled with UHPC with different performances, the pulled chord member is filled with UHPC doped with steel fibers, and the pressed chord member is filled with UHPC doped with coarse aggregates; a novel welding seam arrangement mode is adopted at the chord member butt joint position of the continuous trussed beam. The material strength is higher, the section combination effect is good, and the spanning capacity of the truss girder is higher; the material performance of the chord member is fully exerted; the structure self-weight is small, and effective bearing capacity is large; the damage of welding to concrete in the pipe is small; construction is convenient, the quality is controllable, and the safety degree is high.
本发明涉及一种高强钢管超高性能混凝土简支、连续桁梁，包括由受压弦杆、腹杆与受拉弦杆固定组成的高强钢管桁梁，所述受压和受拉弦杆填充不同性能的UHPC，其中所述受拉弦杆内部灌注有掺钢纤维的UHPC，所述受压弦杆内部灌注有掺粗骨料的UHPC；所述连续桁梁在弦杆对接处采用新型焊缝布置方式。材料强度更高，截面组合效应好，桁梁跨越能力更强；充分发挥弦杆的材料性能；结构自重小、有效承载力大；焊接对管内混凝土的损伤小；施工便捷、质量可控、安全度高。
