More frequent storms

Load-bearing structures can weaken over time

In the future, stormy weather with high wind speeds will occur more frequently and for more extended periods than before. There may be a risk that storms will emerge with a more violent force, which causes buildings to be exposed to extreme conditions more frequently than today. These storms may reveal if the dimensioning and execution of them were correct or if the structures have weakened for one reason or another and, therefore, no longer have sufficient load-bearing capacity.

There is good reason to examine and, if necessary, strengthen weak or inadequate constructions before nature tests them.

A review of the damage after the storm in 1999 showed that the damaged houses had not been built per the standard requirements of the time. However, only a few construction and assembly types accounted for most of the storm damage.

The ravages of time can eventually weaken all constructions. Wood degradation can occur by rot, fungi, or insect attacks. Concrete can be frost-blasted, and rebar corroded by rust. Spalling can occur with masonry, and masonry ties can corrode. Improving and preventing the breakdown of vital structures is essential in maintaining existing real estate.

Strong winds affect roofs, gables, and facades with both direct wind pressure in the windward direction and negative pressure in the leeward direction. Therefore, building owners must continuously ensure that these structures are intact and undamaged and, if necessary, provide a better anchoring of roofs, gables, and other building parts affected by wind pressure. Consider removing large trees that may fall on buildings.
