摘要

抗震结构的线性和非线性反应时程分析是一种越来越多地应用于实践和规范的工具。本文采用谱表示方法对12个加速度信号进行了数值生成。从地震记录数据库中选择另一组15个加速度图，用均匀因子进行缩放，使平均谱与设计谱相吻合。得到了两种不同刚度和阻力框架在两组加速度作用下的非线性动力响应。整体力-位移结果表明，对于一组记录的加速度，特别是对于具有强烈非线性侵入的低阻力结构，其变异系数较高。梁和柱截面的弯矩-曲率关系也有相同的趋势，与整体结果相比具有更高的色散。此外，还分析了竖向加速度分量的影响，竖向加速度分量对框架内柱的影响较大。

Comparison of non-linear dynamic frame response under recorded and numerically generated accelerograms

The time history analysis of the linear and non-linear response of earthquake resistant structures is a tool increasingly used in practice and required by codes. In this paper, a set of 12 accelerograms was generated numerically with the spectral representation methodology. Another set of 15 accelerograms were selected from a database of earthquake records and scaled with a uniform factor so that the mean spectrum fits the design one. The non-linear dynamic response of two frames of different stiffness and resistance was obtained under the action of the two sets of accelerograms. The global force - displacement results showed a higher coefficient of variation for the set of recorded accelerograms, especially for the structure of lower resistance that has a strong non-linear incursion. The same tendency was obtained for the moment - curvature relationships of beam and column sections, with higher dispersions compared to the global results. In addition, the influence of the vertical acceleration component was analyzed, resulting in a higher incidence in the interior columns of the frames.

期刊介绍： The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges. OBJECTIVES The objectives of the Journal of Construction are: 1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.). 2. To provide professionals in the area with material for discussion to refresh and update their knowledge. 3. To disseminate new applied technologies in construction nationally and internationally. 4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
