Article Preview

Field measurements of dynamic characteristics of the multi-storey reinforced concrete frame structure buildings were carried out, by using the ambient vibration test technique, and structural modal parameters were extracted. The measured results and calculated results in accordance with current design specifications were compared. Results show that for multi-storey reinforced concrete frame structure, the measured vibration period of structure is close to the natural period calculated in accordance with the empirical formula of the “Load Code for the Design of Building Structures”. In the actual project, when the designer calculate the natural period if considering only the quality of the infill walls, without considering the stiffness of the infill walls, the period should be shortened. In this paper, the recommended period shortening factor for the multi-storey reinforced concrete frame structure is gave 0.4~0.5.
