ACI 530-2005 Building Code Requirements for Masonry Structures

ACI 530-2005 Building Code Requirements for Masonry Structures. Shear wall, intermediate reinforced masonry A masonry shear wall designed to resist lateral forces while considering stresses in reinforcement and to satis specific minimum reinforcement and connection requirements. Shear wall, ordinary plain (unreinforced) masonry A masonry shear wall designed to resist lateral forces while neglecting stresses in reinforcement, if present. Shear wall, ordinary reinforced masonry A masonry shear wall designed to resist lateral forces while considering stresses in reinforcement and satisf’ing prescriptive reinforcement and connection requirements. Shear wall, special reinforced masoni — A masonry shear wall designed to resist lateral forces while considering stresses in reinforcement and to satisf special reinforcement and connection requirements. Special boundary elements Ln walls that are designed to resist in-plane load, end regions that are strengthened by reinforcement and are detailed to meet specific requirements, and may or may not be thicker than the wall, Spec/led compressive strength of masonry, f ‘. Minimum compressive strength, expressed as force per unit of net cross-sectional area, required of the masonry used in construction by the contract documents, and upon which the project design is based. Whenever the quantityf. is under the radical sign, the square root of numerical value only is intended and the result has units of psi (MPa). Stack bond — For the purpose of this Code, stack bond is other than running bond. Usually the placement of units is such that the head joints in successive courses are vertically aligned. Stirrup Reinforcement used to resist shear in a flexural member. Stone masonry Masonry composed of field, quarried, or cas stone units bonded by mortar, Stone masonry. ashlar Stone masonry composed of rectangular units having sawed, dressed, or squared bed surfaces and bonded by mortar. Stone masonry, rubble Stone masonry composed of irregular-shaped units bonded by mortar. Strength-reduction factor. – – The factor by which the nominal strength is multiplied to obtain the design strength. Tendon anchorage In post-tensioning, a device used to anchor the prestressing tendon to the masonry or concrete member; in pretensioning, a device used to anchor the prestressing tendon during hardening of masonry mortar, grout, prestressing grout, or concrete.ACI 530 pdf download.
