摘要

无震细部钢筋混凝土建筑的抗震性能评价要求采用合适的梁柱节点分析建模方法，梁柱节点是最脆弱的部位。本文研究了梁柱节点建模假设对非延性钢筋混凝土建筑性能评价的影响。数值模拟模型包括梁柱连接的桁架单元和梁柱连接的纤维单元。采用增量动力分析方法对某既有钢筋混凝土建筑的二维四层和六层钢筋混凝土框架进行了设计和分析。将柱弦旋转和相应应变与非延性钢筋混凝土框架性能评估规范的规定进行了比较。

Effect of Modeling Beam-Column Joints on Performance Assessment of Columns in Non-Ductile RC Frames

Seismic performance evaluation of non-seismically detailed reinforced concrete buildings requires proper analytical modeling approaches for beam-column joints which are most vulnerable parts. This study investigates the influence of beam column joint modeling assumptions on performance evaluation of non-ductile RC buildings. Numerical simulation model includes truss-based elements for beam-column connections and fiber-based elements for beams and columns. Two-dimensional four- and six- story reinforced concrete frames of an existing RC building are designed and analyzed by conducting incremental dynamic analyses. Column chord rotations and corresponding strains are compared with code provisions for performance assessment of non-ductile RC frames.

期刊介绍： The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed. Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering. Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
