So as to avoid the formation of galvanic piles on the contact points between the longitudinal and shear steel, those points were covered with an estructurass tape.

The cracking pattern is shown in Figure 7where we can notice the contribution of fixing stirrups every mm that produced major cracking in the tensile zone, due to heavier loads which are similar to the ones causing the shear strength failure. Jason Weiss y Surendra P. Two series of eight beam specimens were reforzafo, each series having a stirrup spacing distance of and mm.
Beams damage induction 2. Estrkcturas About Help Search. R Park ; T Paulay Publisher: It affects the shear strength due to diagonal tensile stress in the structure, which is expected to support high concentration of tensile strength next to bearings. Cancel Forgot your password? Your rating has been recorded. From Cylinders of x mm, which were exposed under dampening and drying eyeles, a concentration of water-soluble chlorides at 10 mm depth of 0.
The curing membrane was removed from side faces by using a metallic bristle brush.
However their resistance will depend as much cncreto the concrete strength as well as on reinforcement strength. Beams were cured for 7 days with a water sheet inside forms; then beams were unmolded and covered with a curing compound up to 28 days of age. However, there are an increasing number of environmental problems, depending on the place where the structure is exposed.

Please enter your name. It was observed that dry environment favors cracking faster than dampening environments. In other research Vidal et al. Besides, wire was replaced by nylon strips in order to hold flexure and shear reinforcements.

Some features of WorldCat will not be available. American Society for Testing and Materials, Philadelphia. They found that reinforced confreto beams rapidly produced the first cracking failures; but those kept at a low growing rate. Recently, Torres-Acosta et al. Control beams failure was caused by shear strength due to diagonal tensile stress.

It is also concluded that stirrups spacing distance did not influence ductility of tested beams. The E-mail message field is required.
These foams are dampened with NaCI solution every three hours during the dampening cycle, in order to avoid the solution evaporation; beams are covered with a plastic film. As expected, the beams which were heavily shear reinforced spacing of mmshowed higher ductility capacity.

R Park ; T Paulay Find more information about: This indicates that beams refoorzado stirrups spacing of mm are most likely to reach an incipient corrosion level depassivation of reinforced steelin comparison to mm spacing distance ones. Therefore, cracking width must be taken into consideration at durability design of reinforced concrete structures.
