Space structure are structure that have three dimension as their behaviors couldn’t to precast. To this definition many of frames such as some archs and brick cupolas are member of this bundle, but in here our scope are the special three dimension that usually have straight part whit rigid junctions or hinges. These constructions in ideal situation should build by same parts or right- angle triangle. Finally a regular several part structure will be shape. These process will be repeat to concoct a strength net-structure solidity of spacious make a special feature to portage big intensive and non concurrent forces. Additionally spacious are suitable for coliseums, showrooms, hangars,
industrial factories, mosques and generally in structures that have limitation in centric base and display features of architecturing arts and constructions trait.
Nowadays spacious growth in architectures and engineers mind. This is’nt completely for sheen and suction rather many causes such as good behavior
against earthquect by reducing mass of structures, good supple to design, possibility of conveyance, strength to dynamic forces, transmission of
installations and etc. in this direct after quantification of spacious, proceed to detail of implementation of these structures and creation solidarity between construction and architecturing and finally ceration of architecture space by submitting case studys.
