摘要

异形柱结构体系在建筑设计和实际使用方面都比矩形柱结构体系有更多的优点。混凝土异形柱结构作为一种较新的结构形式，还没有积累足够的工程实践经验。定义了异形柱框架单元塑性铰的弯矩曲线，研究了应用于框架单元的耦合PMM铰，绘制了铰的屈服曲面。在此基础上，对12层异形柱框架模型进行弹塑性推覆分析，模拟其在不同地震作用下的破坏，研究其抗震性能。本文的工作可为异形柱框架结构的工程应用提供参考。

Research on 3D elastoplastic seismic performance of reinforced concrete special-shaped column frame

The special-shaped column structure system has more advantages than the rectangular column system in terms of architectural design and actual use. As a relatively new structural form, the concrete special-shaped column structure has not accumulated enough engineering practical experience. In this study, the rotation-moment curve of the plastic hinge of special-shaped column frame element was defined, the coupled PMM hinge applied to the frame element was studied, and the yield surface of the hinge was drawn. On this basis, an elastoplastic pushover analysis was conducted on a 12-storey special-shaped column frame model, its failure under different earthquakes was simulated, and its seismic performance was studied. The work of this article can provide reference for the engineering application of special-shaped column frame structure.

期刊介绍： International Journal of Numerical Methods for Calculation and Design in Engineering (RIMNI) contributes to the spread of theoretical advances and practical applications of numerical methods in engineering and other applied sciences. RIMNI publishes articles written in Spanish, Portuguese and English. The scope of the journal includes mathematical and numerical models of engineering problems, development and application of numerical methods, advances in software, computer design innovations, educational aspects of numerical methods, etc. RIMNI is an essential source of information for scientifics and engineers in numerical methods theory and applications. RIMNI contributes to the interdisciplinar exchange and thus shortens the distance between theoretical developments and practical applications.
