Wind Load Algorithm

Overview

This document describes the functions for calculating wind loads in a building structure. The calculations consider factors like wind exposure, internal pressure, and specific building characteristics.

get_wind_topographic_factor

Implementation: Assigns the provided ct value to wind_load.factor.ct.

• Purpose: Sets the topographic factor for wind load.

• Parameters: wind_load, ct (default = 1)

get_wind_exposure_factor

Implementation: Determines ce and cei based on building height, openings, and WindExposureFactorSelections.

• Purpose: Calculates the wind exposure factor.

• Parameters: wind_load, selection, building, manual

get_internal_pressure

Implementation: Uses lw, q, and other factors to calculate positive and negative internal pressure based on InternalPressureSelections.

• Purpose: Computes the internal pressure of a building.

• Parameters: wind_load, selection, lw, q

get_external_pressure

Implementation: Determines the external pressure on various building zones (roof, walls) using a match case structure and assigns them to respective zones in wind_load.

• Purpose: Calculates the external pressure on different zones of a building.

• Parameters: wind_load, lw, q
