摘要

这项研究计算了具有细长结构件和均匀分布荷载的二维框架的倒塌荷载和倒塌机理。崩溃机理和崩溃载荷的搜索采用分步法：载荷系数不断增大，每一步都必须满足平衡方程和相容方程的要求，即在任何截面上都不能超过塑性力矩值。经过验证，无论是从定性还是定量的角度来看，点荷载和均匀分布荷载的结果都是不同的。

Limit analysis of planar steel frames, in-element plastic-hinge for uniformly distributed loads

This work calculates the collapse load and collapse mechanism of 2D frames with slender structural members and uniformly distributed loads. The search for the collapse mechanism and the collapse load is carried out using step by step method: the load factor is increased and at each step the balance and compatibility equations must be satisfied that the value of the plastic moment is not exceeded in any section. It is verified that the results are different in the cases of point loads and uniform distributed loads, both from a qualitative and quantitative point of view.

期刊介绍： The International Journal of Non-Linear Mechanics provides a specific medium for dissemination of high-quality research results in the various areas of theoretical, applied, and experimental mechanics of solids, fluids, structures, and systems where the phenomena are inherently non-linear. The journal brings together original results in non-linear problems in elasticity, plasticity, dynamics, vibrations, wave-propagation, rheology, fluid-structure interaction systems, stability, biomechanics, micro- and nano-structures, materials, metamaterials, and in other diverse areas. Papers may be analytical, computational or experimental in nature. Treatments of non-linear differential equations wherein solutions and properties of solutions are emphasized but physical aspects are not adequately relevant, will not be considered for possible publication. Both deterministic and stochastic approaches are fostered. Contributions pertaining to both established and emerging fields are encouraged.
