The results preliminarily indicate that the open hoop reinforcement form influences some features of structure such as bearing capacity, rigidity and ductility in sliding formwork construction.

The steps of assuring the quality of hoop close of frame beam nodes;

By means of simulating cross-sectional moment-curvature relations of 10 reinforced concrete columns, the predictions of six hoop-confined concrete models are compared with experimental results, showing that the SR model is more accurate than the others for members under compression and moment.

The results show that there is the influence of the flank and the hoop and the arch to the ultimate bearing capacity of the weakened section of the joint.

Analysis on shearing capacity of concrete beams with corroded stirrups;

Influence of the stirrup on corrosive expanding of the concrete building units;

Experimental tests on six slab-column connections with cross-shaped section columns, (three without shear reinforcement, and the remainders with stud shear reinforcements or stirrups) and two relative slab-column connections with square columns were carried out to research into the punching shear of the connections strength and compare the punching shear strength of stud and stirrups.

The effect of stirrups in concrete structure holds the balance, and it has large influence on the performance of structure after corrosion.

Considering the change of the spacing and diameter of stirrups,a corrosion-induced cracking module for concrete members is built by ANSYS.
