The ACUDO software is developed by CTICM which is spreadsheet based software that can be used for structural design analysis.
ACUDO software help for considering the impact of water accumulation process in a building roof tied by defining, via a repetitive method, the final condition of the system studied.
This software is evolved from the part of a study circulated in the journal Steel Construction No. 1- 2010 (CTICM). “Effect of water accumulation in the horizontal valleys of pitched roofs symmetrical gently sloping “(TM. Nguyen, Y. Galéa Mr. Lukic).
The studied pattern is dependent on a load that happens from a combination of shares (generally at Ultimate Limit State). The created load is defined with a equal surface charge and circulated during the roof slope (dead loads, snow, …).
A surface load that is dispersed over a rectangular area (snow accumulation, maintenance, …). Surely an preliminary charge of water, described by the maximum height over the un-deformed assumed roof (level of the overflow or the roof edge, the stationary level in view of the discharge flow rate of the water pipes …).
