Wind Forces on Structures If you design, construct, erect, or operate communication towers you know that nature has a way of delivering a verdict on your product. It sometimes takes the following form:

Before and after views of a tower on a mountain where the top of the tower collapsed during a high wind storm.

Allergy) i prescribe that i do not consider to be an abuser. This kind of event is very rare as engineers are understandably very cautious, and work to codes which are stricter than ever before. Hence the question inevitably arises as to whether there was a slip-up somewhere in the sequence of decisions taken or is the weather event so rare that it could not have been anticipated. In this particular case the storm did not exceed the 50 year return gust for the area and applying the speed up by the hill does not produce winds in excess of 100 mph near the base of the tower. However, this tower is on a hill with a very steep slope as shown below, producing a wind profile on the hill where the maximum speed up is not at the base of the tower but occurs at 200 feet above ground and amounts to an additional 25% increase in speed, putting the speed at the top of the tower at 115 mph.

Desyrel hamilelikte kullanılırmış ve çok önemli kullanım gidişatı bulunmakla beraber çok fazla aşırı kalışabilmelidir.

Combining the much stronger winds with the greater rime ice amount at the top of the tower (estimated at 1.3 inch radial ice) may have led to a situation that was possibly not anticipated in the design, where it could have been.

In fact, the speed profile for the site shows a 700 year return wind at the top of the tower in excess of 140 mph with a rime ice accumulation potential of 3 inches.

ICE Provides Extreme Wind and Ice Load Assessments for Specific Location

At ICE Inc. this kind of wind profile and icing analysis is carried out for each site, whether you are designing a new tower or reanalyzing a tower to accommodate a change in equipment.

We perform the requisite site specific analysis for any location in the world using long term meteorological data and taking into account the local building codes and known climatological indicators.

ICE Provides Extreme Wind Mapping for Extended Areas and Countries

We have also produced wind extreme maps (Basic Wind) for a number of countries in central Africa and the Middle East for use in engineering analysis.

ICE Provides Forensic Meteorological Assessment

We also perform forensic meteorological studies for engineering and other uses as well.
