十字型框架节点加固承载力研究

On enforcement of node in cross-framework

以核心区没有配箍筋的十字型框架节点为研究对象,研究了加固对试件极限承载力的影响程度,借鉴以往加固试验的试验模型,建立节点有限元模型,用ANSYS结构分析软件对模型进行了非线性分析,以期得到试件的极限承载力性能。

This article takes node in cross framework in core area without hoop reinforcement as example, analyzes effect of enforcement on ultimate bearing capacity of the specimen, establishes finite element model by using the old enforcing model for reference, and make nonlinear analysis on the model by using ANSYS in order to obtain the ultimate bearing capacity of the specimen.
