EFFECT OF LOAD BEHAVIOR ON THE STABILITY OF ARCH-SHAPED STRUCTURES,
Abstract
The stability of a hinge-supported arched structure under a two-fold symmetrical load is studied. In one case the forces are always directed along the bisectors of the angles formed by the base and cross beam; in the other, the load preserves its initial direction. The following conditions are given: (a) the members of the structure are considered to be rigid; (b) at the instant of loss of stability the deformations in the structure are small and 2nd-order terms can be ignored. Two situations are considered: one in which the deformation is symmetric and one in which it is skew-symmetric. It is concluded that with a load of constant direction a skew-symmetric deformation is the most serious. For a given ratio of lengths of base and cross beam a symmetric deformation is most serious if the structure is very steep.
