Description

I had been working on Dynamics of multi-storied structure i.e. Equivalent Static Analysis, Response Spectrum Analysis(El-centro Ground Motion),Time History Analysis((El-centro Ground Motion) and Wind Load Analysis after calculation of loads post-processing results show a roof nodal deflection of almost 2 meters,
I request to help me sort out in reduction of immense deflection...
