✦ Synopsis

Vibration measurements were performed on two adjacent, three-storey reinforced concrete frame buildings with hollow clay brick in"ll panels. The "rst building was a bare frame, and the second one was a similar frame in"lled with brick panels. The fundamental period for the in"lled frame building was much smaller than that of the bare frame building. Using shear beam lumped mass models and the vibration data, the actual lateral sti!ness of both buildings was identi"ed. The lateral sti!ness of the in"lled frame building was found to be seven times that of the bare frame building. Four numerical models of the in"lled frame building were constructed. The frame and #oors were represented using an experimentally validated model, and the in"ll panels by one of three commonly used &equivalent diagonal truss' models or by plane stress "nite elements. Only the plane stress "nite element model produced a reasonable agreement with the experimental results.
