Free Form Shell Roof

This study develops a computational model of free form shell generation in the design of roof structures that rely on the optimized behavior of the membrane theory of thin shells.
Free form shell roof. In this video creating a free form facade element is explained by using archicad shell too. Three layers of cloth dipped in a spe cial liquid membrane solution we r e placed over the joint. The roof is curved and used to cover large one story buildings. High resolution version of our famous shell tool in action video.
For effective design it is necessary to use relevant software applications where spatial reasoning is crucial for ordering the three dimensional space by means of simplified engineering models. A shell roof is a common type of roof that is made from thin material. Researchers have been worked with wind actions on structures by using computational simulations and comparing the numerical results with the wind tunnel tests for scale models. As it usually is aesthetically pleasing a shell roof is commonly used in public buildings.
However various interdisciplinary problems related to architectural shaping of free forms and static and strength work thin walled shell sheeting roofs must be solved. The roof structure consists of a free form thin shell dome conforming to a series of spherical surfaces tangential at the junction. For architects and engineers the model offers a low cost fast and relatively easy design solution. Free form shell structures for roofing are related to better structural functionality and can have aerodynamic behavior more efficient and effective than other structures.
Free edge stresses are resisted by an anchor ring reinforced and prestressed along the perimeter of the shell.
