Liang Kuan Since the landlord said that he would be a girder, Liang Kuan suggested that the girder size should be 250X600 when the girder size is ≥250mm.
Second: the beam reinforcement must provide the bending moment and shear force at the beam end. I can calculate the reinforcement for you through calculation. If you don't know, you can provide me with drawings.
Reason: First of all, you need to tell me which earthquake level your area belongs to, because the earthquake will produce horizontal shear, so it will affect the shear calculation of beams.
Is there a infilled wall on the secondary beam? If it is necessary to transfer the linear load to the beam, it will affect the bending moment of the beam.
Third, the size of the columns at both ends of this frame beam, because the shear force and bending moment will be generated at both ends of the columns under the earthquake.
Fourthly, this frame beam belongs to several levels of force transmission. If there are many secondary beams on it, the force on the secondary beams will eventually be transferred to the main beam.
What is the thickness of the fifth board? Because the one-way slab transmits force to the short side, the beam on the short side is finally stressed. Wait a minute.
Sixth, many comprehensive reasons will affect the calculation of beams.
