Design, fabricate, test, and develop a self-connecting cast steel connection for modular steel buildings.

目前的模块化建筑设计使用名为VectorBloc的铸钢连接件进行模块间连接。这种铸钢连接件可实现高精度安装，但这种连接件依赖于高强度内六角螺钉（SHCS）进行垂直连接。本研究旨在开发VectorBloc连接件中的自连接连接件，以消除高强度帽螺钉的使用。具体而言，本项目将设计、制造、测试和开发用于模块化钢建筑的自连接铸钢连接件。结果将有助于消除使用SHCS，这需要一个昂贵和困难的预压过程，同时帮助建筑业提高效率的建设。

Current modular building designs use a cast steel connector called VectorBloc for its intermodular connection.This cast steel connector enables high precision in the installation, however, this connector relies on highstrength socket head cap screws (SHCS) for vertical connection. This research aims at developing aself-connecting connection in the VectorBloc connector to eliminate the use of high strength cap screws.Specifically, this project will design, fabricate, test, and develop a self-connecting cast steel connection formodular steel buildings. The outcome will help eliminate the use of SHCS which require an expensive anddifficult preloading process while helping the construction industry increase efficiencies of builds.
