目前钢柱结构设计中主要采用H型钢柱为主要建材，尽管在一定程度上能够节约钢材，但是钢柱作为工程的重要材料，在历次较大的地震中均有不同范围、不同程度的损坏。H型钢柱建材无法在地震作用下保持柱子的轴力不变，造成H型钢柱的弹塑性下降，降低了建筑的安全性，影响了工程建材性能的发挥。为此，提出H型钢柱的线性梁柱单元动力弹塑性与抗震屈服相关性分析，将H型钢柱的线性梁柱通过弯矩作用于切面平面内，建立对比柱以获得轧制H型钢柱抗震性能的参考数据。从而对H型钢柱的线性梁柱单元动力弹塑性与抗震屈服进行系统分析。根据模型数据进行仿真实验，仿真实验表明，建材所受弯矩越大，切面塑性的区域就越大，H型钢柱的弹塑性与抗震屈服效果就越强。通过分析计算切面H型钢柱，且造价比较低，承载能力比较高，使其可提供一个较高的强度与自重比，使H型钢柱得到更广泛的应用。

Mainly used in steel structure design of H steel column as main materials, although to a certain extent can save steel, but steel column as an important building material, engineering in all previous larger earthquake have different scope, different degree of damage. H section steel column building materials don't columns under seismic action of axial force basic remain unchanged, H section steel column seismic performance decline phenomenon, reduce the security of the building, the impact on the development of engineering building materials performance. Therefore, H section steel column linear beam-column elements related to dynamic elastoplastic seismic yield analysis, H section steel column linear beams through strong bending moment acting on the axial plane, establish contrast column for rolling h-beam column seismic per?formance of reference data. Data according to the model simulation, the simulation experiments show that the H steel col?umn under seismic action may cause the local destruction, does not alter the elastoplastic mechanical performance of the H steel column, local constraints can effectively prevent or delay the H steel column in the elastic and plastic area.
