Question:

Remove the larger span of the beam pillar template why should be removed from the middle to the two ends

nan

Answer:

Remove from the ends of beams began to load, is Liang Hezhu nodes under pure shear, a shear deformation from the middle split beam gradually remove support, after the load is gradually increased, the shear in the support under the protection of gradually increasing load, small impact.
The maximum bending moment in the middle of the beam is removed from the middle of the support, the stress is concentrated on the two supporting end, and the final force form is the same as the reinforcement of the beam, and the bending and the excessive shear force are not generated
When the formwork of the beam is not removed, the load of the beam is evenly distributed. If the two ends of the span from the demolition of the words, the load is borne by the beam at both ends of the column and the template in the cross, when the removal of the template in the cross, the beam is likely to produce cracks and damage. Only from the cross to the ends of the removal, the load is evenly distributed to the ends of the column, the beam will not be destroyed.
