修订后的第5号技术摘要将有助于确定钢龙骨支撑的混凝土板框架系统在人类活动（包括导致地板振动的步行和有节奏的活动）下的响应。这份58页的出版物由Thomas M.Murray博士和Brad Davis博士开发，并由SJI研究和工程实践委员会审查。内容基于西奥多·加兰博斯博士的历史著作，加兰博斯博士曾是钢托梁研究所的咨询工程师。

The revised Technical Digest No. 5 will assist in determining the response of steel joist supported concrete slab framing systems subjected to human movement, including walking and rhythmic activities that cause floor vibrations. This 58-page publication was developed by Dr. Thomas M. Murray and Dr. Brad Davis and reviewed by the SJI Research and Engineering Practice Committees. The content was built on the historical work of Dr. Theodore Galambos, former Consulting Engineer to the Steel Joist Institute.
