DEFORMATION CHARACTERISTICS OF RIGIDLY JOINTED SINGLE-LAYER LATTICED DOMES SUBJECTED TO A CONCENTRATED LOAD AND/OR UNIFORM PRESSURE

Abstract

The deflection behavior of rigidly jointed single-layer latticed domes with several triangular networks subjected to a vertical concentrated load and/or uniform pressure have been studied experimentally. On comparing of the experimental results with calculated ones of finite element method, close agreements between them were obtained. The results indicate that the dome tends to buckle more easily as the distributed load increases and that the buckling characteristics depend on the Shell-likeness Factor S. In applying a concentrated load to the apex of the dome, the deflection characteristics standardize those for the other junctions.
