New supplemental structural beam goes between small tie beams. Say column grids are 30'x30', Plank bears on girders both ends, there are small tie beams between columns in the other direction. It would need a big crane to replace the plank, owner only want to replace with concrete slab. I can't do it unless I put in beam gird cut area to 10'x10' , also I need to reinforce the girder since original uniform load turns to be concentrated load. The plank got water penetration since there is no water proof under the topping.
Since I filled plank ends with concrete and add water membrane on top, there would be no further water damage to the "new" plank. There are several options. Fixing the ends of the existing hollow core planks may not be feasible. Depending on the amount of damage to the existing planks, it may not be possible to repair them so that they may be relied upon to perform satisfactorily in the future.
Replacing the damaged units entails use of a large crane which is expensive. Perhaps the plank width could be reduced from eight feet to four feet or less to permit the use of a smaller crane or alternative lifting equipment. Replacing the damaged units with alternate construction may be feasible. Beams at 10' centers spanning between girders could be used in conjunction with lighter slabs.
Girder reinforcement may not be required at all or, if required, may not be unduly expensive. Red Flag This Post Please let us know here why this post is inappropriate.
