Steel-concrete combined section structure of hybrid beam of cable-stayed bridge and preparation method of steel-concrete combined section structure
The invention provides a cable-stayed bridge hybrid beam steel-concrete combined section structure and a preparation method, and relates to the technical field of bridge engineering.The steel-concrete combined section structure comprises a top plate, a bottom plate is arranged below the top plate, a rear bearing plate is arranged between the top plate and the bottom plate, the upper end of the rear bearing plate is connected with the lower surface of the top plate, and the lower end of the rear bearing plate is connected with the upper surface of the bottom plate; the rear bearing plate divides the space between the top plate and the bottom plate into a combination section and a transition section, the thickness of the rear bearing plate is a preset thickness, and the preset thickness of the rear bearing plate is a calculated value obtained by dividing the product of the allowable axial stress of the top plate and the actual thickness of the top plate by the allowable shear stress of the bearing plate. According to the method, the thickness of the rear bearing plate is the preset thickness obtained through calculation, on one hand, the bearing capacity of the rear bearing plate is guaranteed, meanwhile, cost is saved, on the other hand, slippage caused by the small thickness of the rear bearing plate is avoided, slippage in the combined section is prevented, the structural strength of the steel-concrete combined section structure is improved, and the service life is prolonged.
本发明提供了一种斜拉桥混合梁钢混结合段构造及制备方法，涉及桥梁工程技术领域，钢混结合段构造包括顶板，顶板下方设置底板，顶板与底板之间设置后承压板，后承压板上端与顶板下表面连接，后承压板下端与底板上表面连接，后承压板将顶板与底板之间的空间分为结合段及过渡段，后承压板的厚度为预设厚度，后承压板的预设厚度为顶板的容许轴向应力与顶板实际厚度的乘积除以后承压板的容许剪应力的计算值。本发明中，后承压板的厚度为计算所得的预设厚度，一方面在保证后承压板承压能力的同时节省了成本，另一方面避免了因后承压板厚度较小造成的滑移，防止结合段内滑移的发生，提高了钢混结合段构造的结构强度，延长了使用寿命。
