【摘要】：波形腹板組合梁充分利用了混凝土和波形鋼板這兩種材料的優(yōu)點(diǎn)，與傳統(tǒng)的混凝土梁橋相比，其自重較輕，受力合理，施工工期短，，經(jīng)濟(jì)效益和社會(huì)效益較好。為了研究波形腹板組合梁的設(shè)計(jì)方法，本文從理論分析和數(shù)值計(jì)算兩個(gè)方面對(duì)這種新型組合梁進(jìn)行了研究。 本文的主要研究工作如下： 1、結(jié)合國(guó)內(nèi)外的研究現(xiàn)狀，本文針對(duì)波形腹板組合梁的力學(xué)性能進(jìn)行理論分析，主要研究了波形腹板組合梁的抗彎承載力、抗剪承載力、抗扭承載力和剪力滯效應(yīng)，總結(jié)了波形腹板組合梁的基本力學(xué)計(jì)算理論。所總結(jié)的方法可以用于波形腹板組合梁的結(jié)構(gòu)設(shè)計(jì)計(jì)算。 2、波形腹板組合梁橋的受力性能在很大程度上取決于其結(jié)合部，結(jié)合部一般采用剪力連接件進(jìn)行連接。本文主要研究了剪力連接件的構(gòu)造和設(shè)計(jì)方法，以保證波形腹板組合梁的受力性能不受影響。 3、建立某實(shí)橋的有限元模型，對(duì)其力學(xué)性能進(jìn)行分析，并用本文提出的設(shè)計(jì)方法對(duì)其抗彎承載力和抗剪承載力進(jìn)行驗(yàn)算。結(jié)果表明，該波紋腹板組合梁的抗彎承載力和抗剪承載力均滿足現(xiàn)行規(guī)范的要求，說(shuō)明本文提出的設(shè)計(jì)方法有較好的應(yīng)用價(jià)值。
[Abstract]:The corrugated web composite beam makes full use of the advantages of concrete and corrugated steel plate. Compared with the traditional concrete beam bridge, its weight is lighter, the force is reasonable, the construction period is short, and the economic and social benefits are better. In order to study the design method of corrugated web composite beam, this paper studies the new type composite beam from two aspects: theoretical analysis and numerical calculation. The main work of this paper is as follows: 1. According to the current research situation at home and abroad, this paper analyzes the mechanical properties of the corrugated web composite beam theoretically, and mainly studies the bending capacity, shear capacity, torsional capacity and shear lag effect of the wave web composite beam. The basic mechanics calculation theory of corrugated web composite beam is summarized. The method can be used to design and calculate the structure of composite beam with corrugated web. 2. The mechanical performance of the composite beam bridge with corrugated webs depends on the joint to a great extent, and the joint is usually connected by shear joint. In this paper, the construction and design method of shear joint are studied to ensure that the mechanical behavior of the composite beam with corrugated web is not affected. 3. The finite element model of a real bridge is established, its mechanical properties are analyzed, and the flexural and shear bearing capacity are checked by the design method proposed in this paper. The results show that the flexural capacity and shear bearing capacity of the corrugated web composite beam meet the requirements of the current code, which shows that the design method proposed in this paper has good application value.
