Parametric Study Of Gabled Hyperbolic Paraboloid Reinforced Concrete Shell Roof

The structural behavior of the gabled hyperbolic paraboloid (hypar) reinforced concreternshell roof is investigated to use it efficiently. To attain this purpose, the parametric studyrnof the gabled hypar reinforced concrete shell is carried out using the finite elementrnsoftware package SAP2000. From the analysis result membrane shear force increase withrnincreasing shell ratio of the side, shell thickness, ridge beam depth and width, tie beamrnwidth, shell and ridge beam concrete class, and decreasing shell rise to span ratio, edgernbeam depth and width, edge and ridge beam concrete class. Moreover, the displacementrnincrease as shell ratio of the side, ridge beam depth and width and tie beam width increase,rnand shell rise to span ratio, shell thickness, edge beam depth and width, shell, edge beamrnand ridge beam concrete class decrease.
