Title of the articleAnalysis of span wooden arches stability
Abstract.The paper presents experimental results and the numerical study of spatial stability of long-span wooden arches, specifies the actual work of structures under load, we investigate the influence of various factors (such as finite elements, material properties, reinforcement stiffness of bonds) on the calculation of the stability of the arch. During the tests were measured displacement in the plane and the plane of the load. Evaluation was performed on the state of stress as measured deformations of the wood fibers in the various sections. Construction of arches was loaded to the loss of bearing capacity. As a result of field experiments, the dependences between loads and displacements in the plane and out of plane arches, buckling and critical load values, revealed the nature and causes of structural failure. The results of field experiments and compared with the results obtained by numerical experiments. The experimental data were the basis for further verification of the results of calculations by numerical simulation using the software package ANSYS.
Keywords.Long-span glued wooden arch; stability, critical load; the shape of the deformation; experiment; the numerical investigations.
