Whilst buildings of greater than two storeys and buildings with special functions or unusual features are not covered the basic engineering principles remain valid for these and other larger buildings. We strongly recommend an experienced engineer is consulted when designing larger buildings in earthquake zones as there are other aspects of earthquake- resistant design which must also be considered.Of particular importance to earthquake engineers is the principle of ductility (the ability of a structure to deform but still sustain its load and dissipate energy for several load cycles after initial yield during an earthquake) and the necessity of following the strict detailing rules to ensure a building actually behaves in a ductile manner. Designers will need to comply with relevant building codes when designing larger buildings. Many universities offer courses in the design of earthquake resistant buildings.
