A gutter is generally a fixed beneath the edge of a roof to carry off rainwater, or a narrow trough that collects rainwater from the roof of a building to diverts it from the structure, typically into a drain. Reasonable designs reduce the mass of the gutters (~ 16.9%), make it faster and easier to assemble, and gives it consistent strength and integrity (about 10%). New gutter systems are presented according to the results of structural analyses performed by ANSYS and ADAMS/Durability Hot Spots. In addition, the CATIA program can improve the precision of the 3D system simulations. The design of a gutter system installations also needs to comply with the specific rainfall intensities and adequate overflow provisions needs to be provided to prevent water from sides of the roofs during heavy rainfall periods. The principle outcome of this work is a computational design tool that can be used to improve the gutter performance considering a variety of factors (gutter geometry, drainage and rainfall intensity). A good gutter design must satisfy many criteria, including durability, low cost, and ease of repair and cleaning.
