Design of Prestressed Concrete Cylinder Pipedoi:AWWA C304-07本标准规定了内压埋地预应力混凝土圆筒管结构设计中使用的方法.这些方法适用于受工作,瞬态和现场试验荷载及内部压力组合影响的管道设计.本标准的设计程序适用于内径为16英寸的内衬圆筒管.通过60英寸.(410毫米至1520毫米)和内径为24英寸的嵌入式圆筒管.(610...
A new design procedure is presented for prestressed concrete cylinder pipe subjected to internal pressure, external loads, and pipe and fluid weights based on certain limit‐states design criteria. The proposed design criteria consist of: (1) Serviceability limits for crack control in the core and ...
Prestressed concrete cylindrical pipe (PCCP) has been widely used for the distribution of water in communal, industrial, and agricultural systems for a long time. However, as it deteriorates, structural failures have been experienced. Replacing the entire existing PCCP with partial damages is not ...
The strength design grade of PCCP (prestressed concrete cylinder pipe) concrete in South-to-North Water Transfer Project is C50,C55,C60,which belongs to high strength and high performance concrete,the durability of concrete will directly affect the operation safety and service life of PCCP project,...
The control of chloride ingress into the concrete is the primary aim of durability design in marine structures, as it is the chlorides that initiate corrosion of the steel reinforcement. Thus, durability design usually governs the design of reinforced concrete elements in the marine environment, rath...
Improved understanding of internal swelling reactions and temperature/moisture effects on the delayed strains of containment buildings; improved prediction of the evolution of moisture, strain and stress of prestressed concrete containment buildings, during operational and accidental phases. Improved assessment ...
