The Sound of Concrete?
The Sound of Concrete?
(OP)
We have a building retrofit project under construction. It consists of 3 levels of new steel floor framing constructed inside an existing masonry shell. The floors are concrete placed on composite metal deck. Concrete placement was completed 2-1/2 months ago in November. Contractor now reports hearing "thumping and cracking" sounds (in January) that he thinks are coming from the concrete cracking. There are some hairline cracks visible, but nothing out of the ordinary.
Have any of you experienced a situation like this? Any thoughts or insight would be appreciated.

The operative words are "bearing connection as designed." Sometimes slip critical connectors are installed because it is easier and faster. BUT, the number of connectors typically required for a truly slip critical connection are more than for a bearing connection. Thus, the slip resistance is overcome and the connections enter into a bearing connection, what they were originally designed for.
