Testing and Modeling of Reinforced Concrete Coupling Beams (NEES-2012-1100)

<p><strong>Title</strong>: Testing and Modeling of Reinforced Concrete Coupling Beams (NEES-2011-1100)</p> <p><b>Year Of Curation: </b>2013</p> <p><b>Description: </b>An efficient structural system for tall building construction to resist earthquake loads consists of reinforced concrete shear walls connected by coupling beams. Construction of coupling beams that satisfy the strength and detailing requirements set forth in ACI 318-05 for diagonally reinforced coupling beams is cumbersome and costly; therefore, ACI 318-08 provides a new detailing option which aims to improve the constructability while maintaining adequate strength and ductility. Eight half-scale specimens were tested to compare the performance of beams constructed utilizing new and old detailing options, to compare beams with diagonal reinforcement to beams with straight bars at higher aspect ratios, and to assess the impact of reinforced and post-tensioned slabs. Test results indicate that the new detailing approach provides equal, if not improved behavior as compared to the alternative detailing approach and that including a slab had only a modest impact on strength, stiffness, ductility, and observed damage.</p> <p><b>Award: </b>Charles Pankow Foundation CPF 4-06</p> <p><b>PIs & CoPIs: </b>John Wallace</p> <p><b>Dates: </b>March 09, 2007 - January 04, 2013</p> <p><b>Organizations: </b>University of California, Los Angeles, CA, United States</p> <p><b>Facilities: </b>University of California, Los Angeles, CA, United States</p> <p><b>Sponsor: </b>Charles Pankow Foundation - CPF 4-06</p> <p><b>Keywords: </b>coupling beam,testing,modeling,RC,slab,cyclicloading,tallbuildings,core wall</p> <p><b>Publications: </b><br /> Andrew Fry; Ron Klemencic, "CUEE 2010 Paper - Modeling of Diagonally Reinforced Concrete Coupling Beams"<br /> "EERI 2010 Paper - Testing and Modeling of Diagonally Reinforced Concrete Coupling Beams"<br /> "Testing and Modeling of Reinforced Concrete Coupling Beams"</p> <nb:citations></nb:citations>

背景概述

该数据集聚焦于钢筋混凝土连梁的抗震性能测试与建模，通过8个半尺寸试件实验，比较了新旧配筋方案（基于ACI 318-08和ACI 318-05标准）的性能差异，并评估了板的影响。研究发现，新配筋方案在强度、延性和可施工性方面表现相当或更优，而板对性能影响有限，适用于高层建筑核心墙结构的地震抵抗设计。数据集由加州大学洛杉矶分校于2017年发布，资助方为Charles Pankow Foundation。
