| Abstract | Most of the structures in Sri Lanka are designed neglecting the lateral forces that can act on a building due to an earthquake. This work studies the effects of the lateral forces applied by an earthquake on an existing structure modelled using the computer analysis software ETABS. The effects of an earthquake on the construction cost of the structural elements of a building are studied. An existing structure designed only to resist gravity loads is modelled using the computer analysis software ETABS and analysed after applying the lateral forces caused by an earthquake. The failing columns are identified and redesigned to resist the additional earthquake force. The construction cost of the initial model and the redesigned model considering structural elements are calculated and compared to identify any variations. Two separate bills of quantities are presented with the construction cost of the initial structure and the redesigned structure. The results show that there is a 3.33 % increase in the construction cost of the redesigned structure. The buildings in Sri Lanka can be designed to resist the effects of an earthquake without a significant increase in the construction cost. However, the decision to do so is subjective. |
