20、 specification are welcome and should be submitted as a Criteria Change Request (CCR).*PART 1 GENERAL*NOTE: This guide specification covers reinforced and nonreinforced masonry and must be tailored to reflect the type of construction used in the design.In general, reinforced masonry is defined as ma
21、sonry construction which contains vertical bar reinforcement, horizontal bar or joint reinforcement, mortar, and grout combined in a manner that the component materials will act together to resist the design loading conditions. Design will conform to ACI 530/530.1/ASCE 5 BUILDING CODE REQUIREMENTS F
22、OR MASONRY STRUCTURES.Masonry not meeting the above definition but bonded together with mortar and containing, if necessary, the minimum amount of reinforcement for crack control and vertical stiffeners, is classified as nonreinforced masonry.The following information will be shown on the SECTION 04
