将弦支概念引入柱面网壳结构,提出弦支筒壳结构。通过分析弦支筒壳的结构组成,提出按照筒壳结构层数、筒壳网格形式的弦支筒壳分类方法。分析弦支筒壳相比单层筒壳结构所具有的优势。结合辽宁华福印染厂改扩建工程和天津大港干煤棚工程的概况和实际特点,分析采用弦支筒壳结构的可行性,论述弦支筒壳在这两个工程中的应用设计过程和取得的效果。 The concept of chord support is introduced into cylindrical reticulated shell structure, and a chord support shell structure is proposed. By analyzing the structure of the chord support shell, the method of chord support shell classification is proposed according to the number of shell structures and the shell of the shell. The advantages of the chord support shell compared to the single-layer shell structure are analyzed. Based on the general situation and actual characteristics of the renovation and expansion project of Huafu Dyeing and Finishing Plant in Liaoning Province and the dry-roof coal-caverns project in Dagang, Tianjin, the feasibility of using the chord support shell structure is analyzed. The application design process and acquisition of the chord support shell in these two projects are discussed Effect.
