If structure is designed for seismic loads as per current code method, it generally satisfies the strength and
serviceability criteria. But during strong ground shaking, it may undergo total collapse. The PBPD method can prove
better as it prevents total collapse of the structure by designing it for a predetermined failure and yield mechanism
(strong column-weak beam principle). As total collapse is prevented in this method, it is gaining popularity worldwide.
In our country, the method still needs recognition and hence the study aims on proposing a PBPD method for RCC
frames attuned with our code. The PBPD method differs from current code method mainly in terms of analysis, i.e.
calculation of forces and moments. As the analysis method in PBPD method is based on basic equation of equilibrium. It
can be directly implemented. The design can then carry out satisfying the IS 456:2000 code. The PBPD design proposed
for Indian designers is further made clear by designing a 15 story L-shaped RCC frame.
