Title:        Comparison of wind load among BNBC and other codes in different type of areas
Authors:   R. M. Faysal
Abstract: Wind load as a part of lateral load is very important concern in structural analysis. Rationale wind load can be ensured in a structure by following established and tested building codes. In Bangladesh this purpose has been served by BNBC since 1993. The current BNBC 1993 is going to be replaced by an updated BNBC code which is popularly known as BNBC 2010. In this paper both BNBC codes are studied and compared between them as well as with NBC-India- 2005, IBC 2009 and ASCE 7-05 in terms of wind load using a parameter termed as factored total wind pressure. The investigation reveals that wind load in urban areas (Exposure A) according to BNBC 2010 is slightly higher than BNBC 1993. But wind load in obstructed and unobstructed open terrain type areas (Exposure B and C) according to BNBC 2010 is notable lower than BNBC 1993. Further wind load according to BNBC 2010 is exactly equal to wind load according ASCE 7-05 and slightly less than IBC 2009. Again, in urban and obstructed open terrain type areas NBC-India- 2005 is most conservative while BNBC 1993 is most conservative in unobstructed open terrain type areas in terms of wind load among the comparing codes.
