Concrete splitting failure Deteriorated anchor bolt conditions including metal corrosion, lateral movement, and Ioss of protective cementitious grout. In petrochemical facilities, anchor bolts are used to fasten process vessels or machines to a foundation structure, thus allowing the loads to be transmitted to the foundation, and ultimately to the earth.
· In a simply supported reinforced concrete beam, the reinforcement is placed. (a) below the neutral axis (Ans) (b)above the neutral axis. (c) at the neutral axis. (d) any one of these. joint action of steel and concrete, in a reinforced concrete section, depends upon the. (a) bond between concrete and steel bars.
· These cracks may occur in reinforced concrete elements after the hardening state. Flexural cracks are vertical cracks that develop at the tension zone of the member up to their neutral axis. Width of these cracks are usually wider at the mid-span of the member. This is because the maximum strain in reinforcement occurs at this zone. Flexural cracks on …
· In contrast to this, in the reinforced concrete, only portion of concrete above the neutral axis is effective. Since concrete does not cracks, the possibility of steel to rust and concrete to deteriorate is minimized. Absence of cracks results in higher capacity of the structure to bear reversal of stresses, impact, vibration and shock. In pre-stressed concrete beams, …

Reinforced concrete columns are the main load bearing elements of any structure. They support the beams and slabs and transfer the loads to the foundations. Hence they have to be designed and detailed adequately to resist both gravity and lateral loads. In India columns are more abused than other structural elements; minimum size as per codes not provided, rebars are kinked for …

splitting of compression struts within pile caps depends on the amount of confinement, as well as the aspect ratio (height-to- width) of compression struts. The influence of confinement is more gradual than suggested by the ACI Code bearing strength provisions.
