1) The concrete strength grade of bonded steel reinforced base should not be lower than C 15.
2) It is advisable to paste 2-4mm thick steel plates, and paste them in layers when the calculated thickness is greater than 4mm. ..
3) When the steel plate is bonded to the side of the concrete beam, the width of the steel plate should not be greater than 1/3 of the beam height.
4) Anchorage length of bonded steel outside the reinforcement area: not less than 200t(t is the thickness of steel plate), not less than 60cm in tension area, not less than 160 ton in compression area and not less than 48 cm; For seismic reinforcement, long-span structures or structures that may bear repeated loads, additional anchorage measures, such as bolts, should be added to the anchorage zone.
5) The surface of steel plate shall be plastered with M 15 cement mortar, the thickness of which shall be no less than 20mm for beams and no less than 15mm for plates.
6) The reinforcement of the negative bending moment tensile area at the continuous beam support should be determined according to whether there are obstacles such as columns in this section.
