ABSTRACT
The present thesis work deals with comparison of the code provisions in seismic design of building
stipulated in three seismic codes namely; National Building Code of Nepal NBC105:1994, Criteria for
Earthquake Resistance Design of Structure IS1893:2002 and Uniform Building Code UBC1997.
The regulation of design and construction worked out for a region may not be suitable for other regions.
Codal provisions of codes of developed countries may reflect the recent technological development,
which may be incorporated in the other countries for betterment of the construction quality. The base
shear and pattern of its distribution and fundamental time period determined as per codal provisions of
the three codes has been compared. The work presented also emphasizes upon studying the development
of the Nepalese Standard codal provisions regarding buildings. Amendments to be done to these
provisions in the subsequent revisions of the Nepalese Standard have been spotted out.
A typical six storey building has been analyzed for case study using Seismic Coefficient Method and
Nonlinear pushover analysis. The base shear and pattern of its distribution, fundamental time period and
storey displacement has been numerically found out as per codal provisions of the three codes has been
compared. The behavior of building has been compared using nonlinear pushover analysis.
It is concluded that the basic philosophy of the codes of these countries are same, although regulations
might be different. The results of the study indicated that the base shear and period of vibration value by
UBC1997 are higher among other codes. The ductility behavior of building analyzed by UBC1997 is
worse than other two codes. It is observed that the results obtained by the load combination including
dead load and earthquake load are more than other load combinations.
