Due to the structural efficiency and economic benefits, dome-shaped roofs are frequently used for storehouses or stadiums. Even if the dome has the corresponding geometrical shape, it is not easy to estimate wind loads due to the Reynolds number effect. The external pressure coefficients (cpe) depend on the Reynolds numbers and on the slenderness of the structure. EN 1991‑1‑4 [1] can help you to estimate the wind loads on a dome. Based on this, the following article explains how to define a wind load in RFEM. Wind loads of the structure shown in Image 01 can be divided as follows: Wind Load on Wall, Wind Load on Dome.
RF-/TOWER load was extended with force coefficients for rounded profiles of four-sided towers and square-edged profiles of three-sided towers. The force coefficients for rounded profiles are determined using the Reynolds number. Previously, you could only use the rounded profiles for four‑sided towers and the square‑edged profiles for three‑sided towers.
