摘要
拱形结构作为一种传统的建筑结构形式,在建筑、桥梁等工程领域得到广泛应用.传统的双层屋面板拱形结构采用先张法预应力双层板形式:下层板为平板,承受拉力;上层板为拱形板,承受压力.但受限于先张法施工方法以及预应力筋等因素,跨度受到了一定的限制,难以实现更大跨度.本文以传统的双层拱形板屋面为基础,结合更高强度的预应力钢筋、混凝土以及后张拉施工方法,探讨了一种更大跨度的拱形梁屋面的设计方案.
Abstract
As a traditional architecture structural form,arched structures have been widely used in engineering fields,such as architecture and bridge construction.The traditional double-layer roof panel arched structure adopts a pre-tensioned prestressed double-layer panel form:the lower layer is a flat panel that bears tensile force,while the upper layer is an arched panel that bears compressive force.However,due to limitations in the pre-tensioning construction method and prestressed tendons,the span is somewhat restricted,preventing the achievement of larger spans.Based on the traditional double-layer arched roof panel,this article explores a design scheme for a larger-span arched beam roof by combining higher-strength prestressed steel bars,concrete,and post-tensioning construction methods.
