A Method for Design of Oblique Intersection Beams in Roof Structures

Abstract:

Article Preview

To facilitate calculation of a reinforced concrete oblique intersection beams in roof structures, the analysis ignores the interaction between moment and torque of node position, assuming the beam ends as hinge supports. Vertical displacement coefficients were found out by unit-load method, the compatibility equation of displacement was set up by the conditions of equal displacement at nodes, which can finally calculate force diagram of beams, and further design beam section. When designing, it is necessary to note reinforcement calculation should be taken into account the change of beam effective cross-section high caused by longitudinal tension reinforcement layer placed. Compared with the engineering example show that the design method is more simple and accurate, the results can provide a reference for the engineering design and related research.
