摘　　要：To address the insufficient stiffness of the V-shaped reinforced concrete folded plate structure and its construction process causing environmental pollution,a novel assembled monolithic spherical-shaped reinforced concrete ribbed folded plate structure(AMRRFS)was proposed.The advantages of AMRRFS are that its construction process is environmentally friendly while it also exhibits great stability and rigidity.Therefore,an experimental and numerical investigation were conducted on the AMRRFS to investigate its mechanical properties.In addition,the parametric analysis of the AMRRFS was conducted,and some design recommendations were proposed.Under the design load,the experimental findings revealed that AMRRFS possessed excellent mechanical properties.During the overloading phase,the interface between the in situ casting area and the prefabrication area was severely damaged,leading to the loss of the structure’s ability to bear loads.The outcomes from the finite element simulations of AMRRFS closely mirrored the results of the experimental investigation.Based on the parametric analysis,it was recommended that the height of the AMRRFS,the height of the ribs,and the height of the secondary ridge beams shall be 1/7–1/5,1/65–1/50,and 1/34–1/30 of the span,and that the minimum reinforcing ratio for all types of plates shall exceed 1.0%.
