Abstract
The structural behavior of the gabled hyperbolic paraboloid (hypar) reinforced concrete
shell roof is investigated to use it efficiently. To attain this purpose, the parametric study
of the gabled hypar reinforced concrete shell is carried out using the finite element
software package SAP2000. From the analysis result membrane shear force increase with
increasing shell ratio of the side, shell thickness, ridge beam depth and width, tie beam
width, shell and ridge beam concrete class, and decreasing shell rise to span ratio, edge
beam depth and width, edge and ridge beam concrete class. Moreover, the displacement
increase as shell ratio of the side, ridge beam depth and width and tie beam width increase,
and shell rise to span ratio, shell thickness, edge beam depth and width, shell, edge beam
and ridge beam concrete class decrease.
