Performance of Tilt-Up Buildings in the October 1, 1987 Whittier Narrows Earthquake: Data Collection and Analysis

1987年10月1日，惠蒂尔海峡地震 位于加州洛杉矶市中心以东约10英里处。 这 一个设备齐全的地区包括数千座倾斜的建筑物 不同年龄的人经历过强烈的运动，在某些情况下， 大量的损害。 从地震那天开始 约120个可倾翻结构的易腐性能数据 在整个地区收集。 本研究项目整理性能数据，并进行 详细的性能和结构数据 是为损毁较严重的建筑物而收集的。 特别 注意的是前和后San的相对性能 费尔南多地震结构，以评估抗震规范 旨在消除1971年确定的缺陷的规定 活动 这些数据的记录将证明是非常宝贵的， 突出了严重的设计和施工问题，共同这些 并提高未来损失估计的准确性。 这是可取的，因为建筑类型是非常受欢迎的， 低层商业和工业建筑物和房屋许多战略 行业

On October 1, 1987 the Whittier Narrows Earthquake struck approximately 10 miles east of downtown Los Angeles, California. This very well instrumented region includes thousands of tilt-up buildings of varying ages which experienced strong motions and in some cases, significant amounts of damage. Starting the day of the earthquake perishable performance data on approximately 120 tilt-up structures were collected throughout the area. This research project collates the performance data and conducts statistical analyses of it. Detailed performance and structural data are collected for the more seriously damaged structures. Special attention is paid to the relative performance of pre- and post-San Fernando Earthquake structures in order to evaluate seismic code provisions intended to eliminate deficiencies identified in the 1971 event. The documentation of these data will prove invaluable in highlighting serious design and construction problems common to these buildings and in improving the accuracy of future damage estimates. This is desirable because the construction type is very popular for low-rise commercial and industrial buildings and houses many strategic industries.
