Prestress SMA reinforced thin-wall UHPC I-shaped beam and preparation method
The invention discloses a prestress SMA reinforced thin-wall UHPC I-shaped beam and a preparation method. The I-shaped beam comprises a plurality of bodies connected side by side, wherein each body comprises an upper flange, a lower flange and a web connecting the upper flange and the lower flange, SMA lead screws are arranged in the webs, the upper ends and the lower ends of the SMA lead screws are connected with hard insulating plastic thin strips respectively, and the hard insulating plastic thin strips are located in the upper flanges and the lower flanges respectively. According to the I-shaped beam, the shear resistance of the web can be remarkably improved, the rigidity of a component is improved, and the competitiveness of replacing common profile steel in a corrosive environment is improved.
本发明公开了预应力SMA增强薄壁UHPC工字梁及制备方法，工字梁，包括若干并排连接的本体，本体包括上翼缘、下翼缘和连接两者的腹板，腹板内设置SMA丝杆，SMA丝杆上下两端分别连接硬质绝缘塑料细条，硬质绝缘塑料细条分别位于上翼缘、下翼缘内。本发明工字梁可以显著提升腹板的抗剪性能，提升构件刚度，提高在腐蚀性环境下替代普通型钢的竞争力。
