In order to research the hysteretic behavior of six buckling-restrained braces(BRBs)which were fabricated with Chinese Q235B steel and two types of unbonded materials,experimental research on the hysteretic behavior of BRBs under cyclic load were completed.

3 kinds of waterproof binding material were introduced in this paper,involving their performance detection,the compared analysis of their practical service performance by indoor simulation,and their drawing and cutting intensity,which provided foundations.

Based on the bearing capacity experimental investigation of bonded rebar by using the cement based inorganic anchoring material,failure form and mechanism of this material is analyzed.

In order to reduce the probability of bonding and lengthwise direction fold in process of hood-type annealing, choosing hood-type annealing production line of BaoSteel 1220 plant as subject investigated, this thesis puts forward a new suspension type coil stacking version and it has high theoretical sense and use value.

By analysing band steel adhesion phenomenon, the author presents a new method to improve adhesion phenomenon.
