该项目的总体目标是开发和实施实时 用于建筑物的荷载和挠度监测仪器 构造，以更好地理解关键 施工荷载条件，并制定安全指南 与多层加固特别相关的施工实践 混凝土结构。这项工作的基本假设是(1) 建筑失败的主要原因是没有足够的 临时支撑构件，如垂直护岸和横向支撑， (2)实际荷载和挠度历史的调查 项目可以极大地帮助我们理解临界负载 条件，以及(3)这提高了理解和宝贵的价值 信息可以作为改进施工程序的基础 以及安全设计和施工指南。 除了开发和使用的仪器，以及 将收集的新数据，以设计的形式产生切实的结果 指南将包括(至少)对当前版本的建议修改 规范规定的设计荷载，改进的结构建模方法 施工过程中的荷载，计算垂直和垂直荷载的方法 水平冲击载荷，以及建议的实时监控方案 施工过程中的超载和挠度。

The overall goals of this project are to develop and implement real-time load and deflection monitoring instrumentation for buildings during construction, to develop an improved understanding of critical construction loading conditions, and to develop guidelines for safe construction practices specifically associated with multistory reinforced concrete construction. The fundamental hypotheses for this work are (1) that the primary cause of construction failures is inadequacy of the temporary support elements such as vertical shores and lateral bracing, (2) that an investigation of load and deflection histories during actual projects can contribute greatly to our understanding of critical loading conditions, and (3) that this improved understanding and invaluable information can be used as the basis for improved construction procedures and guidelines for safe design and construction. In addition to the instrumentation developed and employed, as well as the new data which will be collected, tangible outcomes in the form of design guidelines will include (at a minimum) suggested modifications to current code-specified design loads, improved methods for modeling structural loads during construction, methods for accounting for vertical and horizontal impact loads, and suggested real-time monitoring schemes for excess load and deflection during construction operations.
