Optimizing the process variables for making cold-rolled ribbed steel wires and bars by orthogonal test;

This paper described the application of neural networks in predicting mechanical properties of cold-rolled ribbed steel wires and bars.

The development prospect of cold rolled ribbed bar and welded reinforced bar fabric;

The application of cold rolled ribbed bar in construction of spot-cast concrete floor-slab;

The application of cold rolled ribbed bar in cast-in-site floor construction;

, Based on the test of 11 model slabs, this paper analyses the property in applied stage of slabs reinforced with welded wire fabric of cold rolled deformed bars, and presents the correcting suggestion on the strength design volume of the bar, and the calculating formulas of crack width and rigidity.

This paper introdrces application of Cold Rolled Deformed Bar in concrete slabs.

Based on the test of 14 model slabs, this paper analyses the property in applied stage and the failure pattern of slabs reinforced with 550 cold rolled deformed bars, and presents the strength design value of the bar.

This paper introduces the advantages of using the cold-rolled ribbed steel fibric in the construction of concrete deck paving of superhighway, and puts forward some items that should pay attention to in adopting this new technique.

Critical reinforcement ratio of concrete beams reinforced by cold-rolled deformed steel bar;

In order to popularize the using of cold-rolled deformed steel bar in concrete pavement,experiment of simply supported concrete standard beams loaded by equal amplitude fatigue loading was studied.

These beams were reinforced by cold-rolled deformed steel bar and made with different reinforcement ratio of 0%, 0.
