摘要

摘要近年来，钢筋水泥混凝土（RCC）框架由于其固有的抗震性能，已成为高地震区建筑中最常用的结构体系之一。然而，对碾压混凝土建筑结构系统在大地震中的动力行为的理解仍然存在不足。本研究在振动台上对四分之一比例的碾压混凝土框架建筑结构进行了试验。已经报道了工程参数的响应，如自然时间周期、阻尼、楼层加速度和损伤模式。本研究使用了1940年EL Centro（NS组件）的时间历史。在柱梁节点内观察到了破坏模式。已经注意到输入信号和输出信号之间的差异，并且发现它们彼此良好一致。

Seismic Analysis of Reinforced Concrete Frame Using Shake Table Test

Abstract Recently, the reinforced cement concrete (RCC) frame has been one of the most commonly used structural systems for buildings in the high seismic region due to its inherent earthquake-resistant property. However, there is still a deficiency in understanding the RCC building structural system dynamic behaviour during significant earthquakes. A 1/4th scaled RCC framed building structure has been tested on the shake table in the present study. The response in terms of engineering parameters like natural time period, damping, story acceleration, and damage pattern have been reported. The 1940 EL-Centro (NS component) time history has been used for the study. The failure patterns were observed within the column-beam joints. The difference between the input signal and the output signal has been noted and found to be in good agreement with each other.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
