A study to determine the probability of structural failure on selected large billboards in Madaluyong City under extreme wind speeds
Billboards are vertical structures which are exposed to wind forces and are designed to withstand these forces even under extreme conditions. Unfortunately, not all billboards constructed are designed to resist extreme wind speeds during typhoons. It has also been observed globally that the typhoons...
