高桩码头装配式节点结合面抗剪设计方法比较
|
摘要
针对我国现行水运工程混凝土结构规范尚无装配式高桩码头节点结合面的抗剪设计方法,比较研究了美标ACI318、欧标EN 1992-1-1、日本装配式建筑规范和我国工民建《装配式混凝土结构设计技术规程》的推荐设计方法。从破坏机理出发总结了影响装配式节点的抗剪能力的主要因素:结合面的粗糙度、键槽作用和纵向钢筋的销栓作用。最后通过典型设计实例,比较不同标准下装配式节点竖向结合面的抗剪能力。建议在需要进行结合面的键槽设计时采用日本装配式建筑规范。
In view of the fact that there is no shear design method for the contact surface of piled wharves prefabricated joint in China 's current code of concrete structure for water transportation engineering, the recommended design methods of American standard ACI318, European standard en1992-1-1, Japanese prefabricated building code and China 's civil code Technical Specification for Precast Concrete Structure are compared and studied. Based on the failure mechanism, the main factors affecting the shear capacity of the fabricated joints are summarized: the roughness of the contact surface,the groove action of the end face,and the pin action of the longitudinal reinforcement. Finally,through the typical design example,the shear capacities of the vertical contact surface of the prefabricated joint for different cods are compared. The Japanese prefabricated building code is recommended for the groove design of the contact surface required.
