Dynamic Amplification of Seismic Moments and Shear Forces in Cantilever Walls

The main aim of this project is to determine appropriate dynamic amplification factor for flexure and shear for a range of cantilever wall buildings of 2, 4, 8, 12, 16 and 20 stories which were designed using displacement-based design principles.

In addition, the relationship between ductility demand and the dynamic amplification factor in each wall system is investigated. This is carried out using time history analyses for five different earthquakes intensities for each wall, and analysing the resulting bending moment shear force and drift envelopes.

The effects of some of the issues discussed above are analysed through the use of inelastic dynamic analyses and the results are compared with existing code requirements.
