Hi, Supposed just for sake of discussion and theoretical understanding, a house with poured reinforced concrete foundation columns and beams are found to have one of the sides trespassing the neighbor due to incorrect land survey before it was constructed. Now the whole say left side of the house will be removed along with the entire left foundations from column base to beam column joint to girders to the roof girder of the second floor and the entire wall. Now supposed you would put a new steel I-beam as column foundation and new girder and new walls. Can you just cut the reinforced concrete beam near the end and just put it on top of the 6 meter I-beam without support at the middle of the beam? What shearing force would be encountered when this beam end is in contact with the I-beam by just putting on top of it and maybe adding a steel staple to connect the two. Let’s say the reinforced I-beam is 1 yard in height and 1 foot in thickness with 6 pcs of 20mm Rebar inside arranged 2 at top, 2 at center and 2 at bottom. I read elsewhere that reinforced concrete beam-column joint has opposing shearing forces at top and bottom of it. But when the end is cut and the rebars are not connected to anything but just imbedded in the beam concrete. And the entire weight of the second floor is supported by the 6 meter beams and the beam ends are cut (removing the original concrete column and joint as described above). Would the end be stable enough to support the weight of the whole concrete and second floor assuming there was no earthquake. What if there is earthquake and there is lateral movement, would the end of the beam just give way? Anyway. How do you attached the cut end of the 6 meter beam to a new column I-beam at the sides to give strength not far from original without having put support to the 6 meter beam halfway? Thanks.
