③ 摘要
本篇文章描述了對(duì)加固后標(biāo)準(zhǔn)尺寸混凝土結(jié)構(gòu)試件進(jìn)行試驗(yàn)的結(jié)果，該試件代表平面框架結(jié)構(gòu)中的梁–柱聯(lián)接部位。設(shè)計(jì)試驗(yàn)的目的是為了研究在靜載條件下纖維增強(qiáng)塑料被應(yīng)用到梁–柱聯(lián)接部位外表面附近時(shí)對(duì)所測(cè)試件的影響。特別令人感興趣的是在靜載條件下應(yīng)用纖維增強(qiáng)塑料對(duì)增強(qiáng)梁–柱聯(lián)接部位所起的作用。作為研究的關(guān)鍵，為了從外部對(duì)混凝土的連接部分進(jìn)行加固，設(shè)計(jì)了帶有E玻璃無(wú)捻粗紗布和碳布的混合纖維增強(qiáng)塑料復(fù)合物，并且該復(fù)合物結(jié)合了短貼原絲氈和帶有乙烯基酯樹(shù)脂的玻璃纖維帶。結(jié)果顯示，對(duì)于應(yīng)用纖維增強(qiáng)塑料改進(jìn)過(guò)的混凝土結(jié)構(gòu)的關(guān)鍵部分能夠?qū)炷两Y(jié)構(gòu)的強(qiáng)度和硬度起到增強(qiáng)的作用，同時(shí)也能夠起到在不同類(lèi)型荷載條件下增強(qiáng)它們的效果。同時(shí)，本篇文章也討論了為改進(jìn)和增強(qiáng)混凝土結(jié)構(gòu)的強(qiáng)度和硬度而如何選擇纖維增強(qiáng)塑料和結(jié)構(gòu)類(lèi)型。

The paper describes the results of tests on prototype size reinforced concrete frame specimens which were designed to represent the column–beam connections in plane frames. The tests were devised to investigate the influence of fibre reinforced plastic (FRP reinforcement applied to external surfaces adjacent to the beam–column connection on the behaviour of the test specimens under static loading. Of particular interest under static loading was the influence of FRP reinforcement on the strength and stiffness of beam–column connection. As a key to the study, the hybrid FRP composites of E-glass woven roving (WR) and plain carbon cloth, combined with chopped strand mat (CSM), glass fiber tape (GFT) with a vinyl-ester resin were designed to externally reinforce the joint of the concrete frame. The results show that retrofitting critical sections of concrete frames with FRP reinforcement can provide signification strengthening and stiffening to concrete frames and improve their behaviour under different types of loading. The selections of types of FRP and the architecture of composites in order to improve the bonding and strength of the retro-fitting were also discussed.
