Walking and heel-drop tests were performed on four floors in a multi-storey building under construction to identify their dynamic response characteristics. A single bay was adopted for the testing in the same corner location. Although all floors were nominally of identical composite RC slab on steel beam design, two were fully fitted out, the third partially and the fourth was a bare floor. Both the Haritos Equal Area Method of spectral fitting and the Randec method were used to perform investigations on single point acceleration response records. Results highlight the complexity of response of floors to human-induced excitation and the rather low values of damping from walking tests compared with estimates from heel-drop excitation.
