BNBC 2020 pdf download, AS A CIVIL ENGINEER, IT’S VERY IMPORTANT TO KNOW ABOUT BUILDING DESIGN CODE. HERE I WILL GIVE YOU THE DOWNLOAD LINK FOR THE BNBC 2020 PDF.
The new edition of Bangladesh’s building code is the Bangladesh National Building Code 2020 (BNBC 2020). The expert panel in relevant fields revises it. This code closely resembles ASCE 7-05. Structural engineering professionals, architects, electrical engineers, fire protection designers, plumbing engineers, mechanical engineers, and planners who wish to work in Bangladesh need BNBC 2020 for the design and construction of infrastructures. While there are some errors in BNBC 2017, it is very useful and helpful for Bangladesh practicing qualified engineers. Earthquake load and wind load, if compared to BNBC 2006, have been substantially revised.
