Experimental Study of Seismic Response of Reinforced Concrete Setback Buildings

<p style="font-style: normal">    "A one-quarter scale model of a two-bay by two-bay, six-story reinforced concrete ductile moment resisting frame having 50 percent setback at mid-height was designed, constructed, and tested. The prototype structure was designed for combined gravity and seismic effects determined according to the requirements of the 1982 Uniform Building Code. Proportion and details were provided to satisfy the seismic provisions of Appendix A of the ACI Building Code (ACI 318-83) and the ACI-ASCE Committee 352 recommendations for design of beam-column connections.</p> <p style="font-style: normal">    The test structure was subjected to a number of tests including static pull-back tests, free-vibration tests, and unidirectional and bidirectional earthquake simulations on the earthquake simulator at the Earthquake Engineering Research Center of the University of California, Berkeley. The base motions modeled records obtained from the 1940 El Centro, 1978 Miyagi-Ken-Oki, or 1985 Mexico City earthquakes. The experimental findings from the response of the test structure were extended to a broad spectrum of response of setback frames."</p> <p style="font-style: normal">-excerpt from reference 1</p> <p>This resource contains data from a six shake table tests of a six-story reinforced concrete special moment-resisting frame (SMRF). </p> <p><img alt="Photo of the test structure" src="https://datacenterhub.org/resources/276/download/2_Structure.png" style="width: 600px; height: 430px; border-width: 1px; border-style: solid" /></p> <p><strong>Notes</strong>:</p> <p>Start Date / End Date: These were taken from the time stamp on the data files.<br /> Latitude / Longitude: This points to the University of California, Berkeley's Earthquake Simulator Laboratory.<br /> Drawings / Photos: The number at the beginning indicates from which reference these were taken.</p> <p><strong>References</strong>:</p> <p>1.    Shahrooz, B. and Moehle, J.

研究设计、制作并测试了一个1/4缩尺比例的两跨×两跨六层钢筋混凝土延性抗弯框架模型，该模型在中高度处设有50%的退台构造。原型结构按照1982版《统一建筑规范》（Uniform Building Code, UBC）的要求，针对重力荷载与地震作用的组合效应进行设计。构件比例与构造细节需满足美国混凝土协会（ACI）建筑规范附录A（ACI 318-83）的抗震条款，以及ACI-ASCE 352委员会关于梁柱节点设计的建议。

试验模型在美国加州大学伯克利分校地震工程研究中心的地震模拟振动台上开展了多项测试，包括静态拉回试验、自由振动试验，以及单向与双向地震模拟试验。输入的基底地震动分别采用1940年埃尔森特罗地震、1978年宫城冲绳近海地震以及1985年墨西哥城地震的实测记录。基于该试验模型的响应得到的实验结论，可推广至各类退台框架的响应分析范畴。
