摘要：In general, the effect of dynamic load is not considered because its consideration in analysis makes the solution more complicated and time consuming. Therefore, the majority of Civil Engineering structures are designed with the assumption that all applied loads are static. This feature of neglecting the dynamic forces may sometimes become the cause of disaster, particularly, in case of earthquake. Some recent earthquakes have shown the need of dynamic analysis. Nowadays, there is a growing interest in the process of designing Civil Engineering structures capable to withstand dynamic loads, particularly, earthquake-induced load.Simple empirical relationships are available in many design codes to relate the height of a building to its fundamental period of vibration. These relationships have been realised for force-based design and so produce conventional estimates of period such that the lateral shear force will be conservatively predicted from an acceleration spectrum. When assessment of a structure is concerned, it is the displacement demand that gives an indication of the damage that can be expected. In this paper, the fundamental periods of a low rise building is studied using empirical formulae from IS 1893(Part 1) and finite element modelling in SeismoStruct. The results are compared and the factors are discussed on which fundamental period of a structure depends.
