Abstract： |
The present invention discloses anti-cracking method in negative hogging moment area of combined steel-concrete beam, and belongs to the field of support beam structure in road, bridge and building. The anti-cracking method includes two steps of depositing concrete in the positive hogging moment area and negative hogging moment area of continuous combined steel-concrete beam, laying pre-pressing load in the positive hogging moment area and introducing pre-pressing stress into concrete wing plate in the negative hogging moment area, so as to prevent cracking of the wing plate concrete and raise the durability of the structure. Compared with available technology, the construction method of the present invention is simple, fast and practical. |
