Abstract :
The structures, or Bridges and Buildings, as
well as their components, must be built to withstand the
prescribed wind loads. Wind load-resisting structures,
including structural components, components, and
cladding, must be designed to withstand shearing, sliding,
overturning, and uplifting forces as a result of wind
forces. Because wind loads are a component of rational
loads, following a standard and tested building code can
be used to provide this function. The Bangladesh
National Building Code (BNBC) and the Japan Road
Association (JRA) were issued in 1993 and 1947,
respectively, to fulfill this purpose in Bangladesh and
Japan, respectively. Because of the way lateral loads are
applied and handled in various codes, the antedated 1993
BNBC is replaced by a subsequent BNBC code that is
commonly named the BNBC 2020, which was issued in
Bangladesh in 2021. In this paper, the BNBC codes are
studied and compared with each other and with JRA
2012, AASHTO 2012, AASHTO 2020, and ASCE 7-05.
The investigation reveals that the percentages of the
basic wind speed increase according to BNBC 1993 and
BNBC 2020 significantly increased compared to the
recent codes, but the investigation also reveals that the
designed wind pressure in different exposures is slightly
higher according to BNBC 1993 than BNBC 2020.
Design wind pressure and applied wind load according
to BNBC 2020 is equal to or higher than ASCE 7-05.
Designed wind pressure is comparatively less and
slightly higher for BNBC 2020 compared to AASHTO
2012 and AASHTO 2020. JRA 2012 has the greatest
design wind pressure value for all the cases. The main
purpose of the study will be to apply wind loads to
bridge structures using BNBC, and then compare these
results with those obtained using other codes as
mentioned in BNBC. Because there is no specific
guideline for the use of wind loads in BNBC.
