    PROJECT: Janathon Bonik, Dhaka Savar: by Engr. Ali Asgor

    Uploaded by

    Mehedi H. Rana
    This document provides calculations of wind load according to the Bangladesh National Building Code (BNBC) for a project in Savar, Dhaka. It includes tables of design wind pressure values for different heights above ground level and wind exposures. It also shows sample calculations of wind load for a structure with given dimensions and height above ground. The wind load is calculated based on factors like wind speed, height, exposure and dimensions of the structure.
