A New Method for Calculating the Internal Force of Anchor Frame Beam and Its Field Test
In order to make the calculation result of internal force of the existing frame beam more consistent with the engineering practice,two methods of theoretical calculation and field test are used to analyze the internal force distribution law of the frame beam.Considering the non-uniformity of frame beam material,a new calculation method is given,and the measured bending moment calculation method is introduced to organize the field test da-ta,and the test results are compared with the theoretical results.The results show that the theoretical results of the distribution trend of the frame beam moment are consistent with the test results.The transformed section method is used to solve the inertia moment of the beam section,and the obtained results can improve the bending resistance of the frame beam and reduce the reinforcement ratio.The anchoring force is an important influencing factor of the internal force of the frame beam.The greater the anchorage force,the greater the bending moment of the frame beam.
