2010年2月27日智利马乌莱地震对几座中高层混凝土墙建筑造成了破坏，这些建筑的性能为结构工程设计提供了实际经验。震后勘测小组观察到的破坏包括钢筋屈曲和墙边界处的混凝土压碎，整体墙屈曲，以及建筑结构问题（如板、梁、拱肩和楼梯的不连续性和耦合）造成的破坏。这种破坏引起了关于导致钢筋屈曲、混凝土压碎和墙体屈曲的物理机制的重要问题。工程师如何解释损坏可能会导致不同的结论，详细必要的弯曲控制墙提供延性。一个由从业人员和研究人员组成的小组正在通过ATC-94项目制定与上述行为有关的建议。本文总结了目前的工作和初步的调查结果，包括震后观察，整个建筑物和个别结构元件的分析研究，以及潜在的变化，以改善设计实践的概念。
The Maule Chile Earthquake of 27 February 2010 caused damage to several mid-rise and high-rise concrete wall buildings, and the performance of these buildings offers practical lessons for structural engineering design. Postearthquake reconnaissance teams observed damage including buckling of reinforcing bars and concrete crushing at wall boundaries, overall wall buckling, and damage resulting from building configuration issues such as discontinuities and coupling from slabs, beams, spandrels, and stairs. This damage raises important questions about the physical mechanisms that lead to bar buckling, concrete crushing, and wall buckling. How engineers interpret the damage can lead to different conclusions about the detailing necessary to provide ductility in flexure-governed walls. A team of practitioners and researchers is developing recommendations related to the behaviors described above through the ATC-94 project. This paper summarizes current work and preliminary findings, including post-earthquake observations, analytical studies of whole buildings and individual structural elements, and concepts for potential changes to improve design practice.
