Simplified Calculation Method of Optimal Centre Line of the Arch

Abstract:

Studied the arch structure under vertical loads reasonable arch axis problem, regardless of the arch on the role of distributed load or concentrated load, the structure can be simplified into line arch, ignoring axial deformation of bars, the moments at the joints must be equal to zero, the ratio of rise to span for the parameters, derived function of the coordinates of each node to determine the arch of the pressure line, and also determine the horizontal thrusts of the arch. The method is simple and practical, especially for the preliminary design stage, for the arch axis provides the basis for further optimization.
