Section 7 -5 -865: INFORMATION REQUIRED ON PLANS. <br /> (a) General. In addition to the seismic analysis required elsewhere in this Article, the <br /> licensed engineer responsible for the seismic analysis of the building shall determine and <br /> record the infomiation required by this section on the approved plans. <br /> (b) Construction Details. The following requirements with appropriate construction details <br /> shall be made part of the approved plans: <br /> (I) All unreinforced masonry walls shall be anchored at the roof level by tension bolts <br /> through the wall as specified in Table A l -E of Appendix A or by approved <br /> equivalent at a maximum anchor spacing of six feet. All unreinforced masonry <br /> walls shall be anchored at all floors with tension bolts through the wall or by <br /> existing rod anchors at the maximum anchor spacing of six feet. All existing rod <br /> anchors shall be secured to the joists to develop the required forces. The Building <br /> Official may require testing to verify the adequacy of the embedded ends of <br /> existing rod anchors. Tests when required shall conform to Section 7 -5- <br /> 1 I55A(h). When access to the exterior face of the masonry wall is prevented by <br /> proximity of an existing building, wall anchors conforming Table Al -E may be <br /> used. <br /> Alternative devices to be used in lieu of tension bolts for masonry wall anchorage <br /> shall be tested as specified in Section 7 -5 -860. <br /> (2) Diaphragm chord stresses of horizontal diaphragms shall be developed in existing <br /> materials or by addition of new materials. <br /> (3) Where trusses and beams other than rafters or joists are supported on masonry, <br /> ledgers or columns shall be installed to support vertical loads of the roof or floor <br /> members. <br /> (4) Parapets and exterior wall appendages not capable of resisting the forces specified <br /> in this Article shall be removed, stabilized or braced to insure that the parapets <br /> and appendages remain in their original position. <br /> (5) All deteriorated mortar joints in unreinforced masonry walls shall be pointed with <br /> Type S or N mortar (Masonry cements shall not be used). Prior to any pointing, <br /> the wall surface must be raked and cleaned to remove loose and deteriorated <br /> mortar. All preparation and pointing shall be done under the continuous <br /> inspection of a special inspector certified to inspect masonry or concrete. At the <br /> conclusion of the project, the inspector shall submit a written report to the <br /> Building Official setting forth the portion of work inspected. <br /> (6) Repair details shall be prepared for any cracked or damaged unreinforced masonry <br /> wall required to resist forces specified in Appendix A. <br /> ORDINANCE NO. 2010 -018 9 <br />
