敞开式桁架梁结构在人类早期建筑发展史中曾经有过广泛的应用。随着当今社会建筑材料、设计理论、施工水平等方面的高速发展,敞开式桁架梁结构以其建筑高度低、造型简洁美观的特点再次引起人们的关注。文章结合某在建高速公路中单跨60m敞开式钢管-混凝土桁架组合梁桥的应用,对敞开式桁架组合梁桥的设计进行了分析和探索,实为抛砖引玉,以期敞开式桁架组合梁桥能得到更好、更多样的发展。
Open truss beam structure in the history of early human development has had a wide range of applications. With the rapid development of today’s society, such as building materials, design theory and construction level, the open truss girder structure attracts people’s attention again due to its low building height and concise appearance. In this paper, based on the application of a single span 60m open steel tube-concrete composite girder bridge under construction in an expressway, the design of the open truss composite girder bridge is analyzed and explored. In fact, the design of open truss composite girder bridge Get better and more diverse.
