Fundamental Time Period Calculator
Posted by Dinesh onThe fundamental time period (T) may either be established by experimental observations on similar buildings or calculated by any rational method of analysis. In the absence of such data, T may be determined as follows for multi-storeyed buildings:
a) For moment, resisting frames without bracing or shear walls for resisting the lateral loads T-=0.1 n
Where, n = number of storeys including basement storeys
b) For all others
T = (0.09 * H ) / √d
Formula:
T = (0.09 × H ) / √d
Where,H - total height of the main structure of the building in metres,
d - maximum base dimension of building in metres in a direction parallel to the applied wind force.
T - the fundamental time period
