波形钢腹板PC组合箱梁充分利用了混凝土抗压、波形钢腹板质轻、抗剪屈服强度高等优点,由于不需要混凝土腹板,从而相应地减少了钢筋和模板的拼装、拆除作业,缩短了工期,而且波形钢腹板PC组合箱梁的整桥具有较强的美感,是城市立交、风景区较好的选择桥型。
Founded on forcing features of the composite box-girder with corrugated steel webs,systemic flexure theory at elastic stage was deduced.
基于波形钢腹板组合箱梁独特的受力特点,建立了系统的弹性阶段受弯分析理论:从弯曲正应变分布的拟平截面假定出发,采用材料力学方法,推导了正应力、剪应力及波形钢腹板承担的剪力占整个截面所受剪力比例的计算公式;运用能量原理推导了挠度的计算公式。
The externally prestressed composite box girder with corrugated steel webs is a new type steel-concrete composite structure.
体外预应力波形钢腹板组合箱梁是一种新型的钢—混凝土组合结构,与传统的预应力混凝土箱梁相比,该结构具有自重轻、受力明确、造型美观、彻底解决混凝土腹板开裂的问题等突出优点。
