orientation. The allowable resistance value of the existing anchors shall be 40 percent of the average of those tested anchors having the same wall thickness and joist orientation. (i) Qualification tests for devices used for wall anchorage shall be tested with the entire tension load carried on the enlarged head at the exterior face of the wall. Bond on the part of the device between the enlarged head and the interior wall face shall be eliminated for the qualification tests. The resistance value assigned the device shall be 20 percent of the average of the ultimate loads. Section 7-5-865: INFORMATION REQUIRED ON PLANS. (a) General. In addition to the seismic analysis required elsewhere in this Article, the licensed engineer responsible for the seismic analysis of the building shall determine and record the information required by this section on the approved plans. (b) Construction Details. The following requirements with appropriate construction details shall be made part of the approved plans: (1) All unreinforced masonry walls shall be anchored at the roof level by tension bolts through the wall as specified in Table AI-E of Appendix A or by approved equivalent at a maximum anchor spacing of six feet. All unreinforced masonry walls shall be anchored at all floors with tension bolts through the wall or by existing rod anchors at the maximum anchor spacing of six feet. All existing rod anchors shall be secured to the joists to develop the required forces. The Building Official may require testing to verify the adequacy of the embedded ends of existing rod anchors. Tests when required shall conform to Section 7-5- 1155A(h). When access to the exterior face of the masonry wall is prevented by proximity of an existing building, wall anchors conforming Table Al-E may be used. Alternative devices to be used in lieu of tension bolts for masonry wall anchorage shall be tested as specified in Section 7-5-860. (2) Diaphragm chord stresses of horizontal diaphragms shall be developed in existing materials or by addition of new materials. (3) Where trusses and beams other than rafters or joists are supported on masonry, ledgers or columns shall be installed to support vertical loads of the roof or floor members. (4) Parapets and exterior wall appendages not capable of resisting the forces specified in this Article shall be removed, stabilized or braced to insure that the parapets and appendages remain in their original position. 9
