Standardization of embedded plates for steel-concrete connections in builinds

在建筑物中，混凝土和钢构件之间的连接通常使用嵌板，嵌板由钢板和锚(钢棒)浇注在混凝土构件中组成。然后，可以将钢夹具焊接到板上，以便将钢构件(例如工字梁)连接到混凝土上。虽然这些板的强度在设计规范中有很好的描述，但它们是如何加载的却没有。嵌入板的设计从一个项目到下一个项目都不同，甚至在同一家工程公司内部也是如此，因为工程师们在设计它们应该抵抗哪些力的问题上存在分歧。这导致在设计室设计板材、在钢铁车间制造板材以及在现场安装板材所需的时间和成本较高。 该项目旨在通过开发和验证新的标准化板材来提高建筑物的成本效益，这些板材可以纳入许多不同的项目，消除了当前做法中常见的重复设计和施工过程。拟议的项目包括在典型加拿大建筑中经历的加载条件下对嵌入板进行计算机模拟和测试。结果将以一种可以在现代三维建筑设计软件中使用的格式进行总结。研究结果将减少设计、制造和安装这些板所花费的时间。这些结果将使所有建筑项目利益相关者受益，从在设计阶段节省时间的设计工程师，到可以更快地制造标准化部件的钢铁制造商，到看到建造时间缩短和现场冲突减少的承包商，以及受益于较低成本的业主。

In buildings, connections between concrete and steel members are commonly made using embedded plates, which consist of a steel plate with anchors (steel rods) cast into a concrete member. Steel fixtures can then be welded onto the plate to allow steel members (e.g., I-beams) to be connected to concrete. Although the strength of these plates is well described in design codes, how they are loaded is not. Embedded plates are designed differently from one project to the next, even within the same engineering firm, because engineers disagree on which forces they should be designed to resist. This leads to poor use of time and higher costs associated with designing plates in design offices, fabricating plates in steel shops, and installing plates on-site. This project aims to improve the cost-effectiveness of buildings by developing and validating new standardized plates that can be incorporated across many different projects, eliminating the redundant design and construction process typical of current practice. The proposed project includes computer simulations and testing of embedded plates subject to loading conditions experienced in typical Canadian buildings. The results will be summarized in a format that can be adapted for use in modern three-dimensional building design software. The study results will reduce the time spent designing, fabricating, and installing these plates. These outcomes will benefit all building project stakeholders, from design engineers who save time at the design phase, to steel fabricators who can more quickly fabricate standardized parts, to contractors who see decreased build times and fewer on-site conflicts, and owners who benefit from lower costs.
