Bolts and dowels to be one-half inch minimum in diameter. (d) Alternate materials. Alternate materials and methods of construction may be approved by the department in accordance with applicable provisions of Chapter 1 of Part 1 of the Uniform Building Code. (e) Minimum acceptable quality of existing unreinforced masonry walls. (~.) General provisions. Ail unreinforced masonry walls utilized to carry vertical loads and seismic forces parallel and perpendicular to the wall plane shall be tested as specified in this section. All masonry quality shall equal or exceed the minimum standards established herein or shall be removed and replaced by new materials. Alternate methods of testing approved by the department may be used. Nothing shall prevent pointing with mortar of all the masonry wall joints before the tests are first made. Prior to any pointing, the mortar joints must be 19 ORDINANCE ~[S-2182 PAGE 20 raked and cleaned to remove loose and deteriorating mortar. All preparation and mortar pointing shall be done under the continuous inspection of the director with a subsequent written report to the department. All testing shall be performed by an approved testing agency in accordance with the requirements specified in this subsection. Exception: Unreinforced masonry walls which carry no design horizontal or vertical loads other than their own weight may be considered as veneer if they are adequately anchored to new supporting elements, in accordance with this section. (2) Number and location of tests. The quality of mortar in all masonry walls shall be determined by performing in place shear tests or by testing eight-inch diameter cores. The minimum number of tests shall be two (2) per wall or line of wall elements resisting a common seismic force, one per one thousand five hundred (1,500) square feet of wall surface, or eight (8) minimum, whichever requires the largest number of tests or cores. The exact test or core location shall be determined at the building site by the licensed engineer or architect responsible for the seismic analysis of the subject building. The results of all tests or coring shall be recorded and reported. (3) In-place shear tests. The bed joints of the outer wythe of the masonry shall be tested in shear by laterally displaying a single brick relative to the adjacent bricks in that wythe. The opposite head joint of the brick to be tested shall be removed and cleaned prior to testing. The minimum quality mortar in eighty (80) per cent of the shear tests shall not be less than the total of thirty (30) psi plus the axial stress in the wall at the point of the test. The shear stress shall be based on the gross area of both bed joints and shall be that at which movement of the brick is first observed. (4) Core tests. A minimum number of mortar test specimens equal to the number of required cores shall be prepared from the cores and tested as specified herein. The mortar joint of the outer wythe of the masonry core shall be tested in shear by placing the circular core section in a compression testing machine with the mortar bed joint rotated fifteen (15) degrees from the axis of the applied load. The mortar joint tested in shear shall have an average ultimate stress based on the gross area of twenty (20) psi. The average shall be made from the total number of cores made. If test specimens cannot be made from the 20 ORDINANCE NS-2182 0~ PAGE 2] total taken the shear value shall be reported as zero. The results of all coring and shear testing shall be reported. (f) Testing of shear bolts. One-fourth (1/4) of all new shear bolts and dowels embedded in unreinforced masonry walls shall be tested by the director using a torque calibrated wrench to the following minimum torques: 1/2" diameter bolts or dowels = 40 foot-lbs. 5/8,' diameter bolts or dowels = 50 foot-lbs. 3/4" diameter bolts or dowels = 60 foot-lbs. No bolts exceeding three-fourths (3/4) inch shall be used. Ail nuts shall be installed over malleable iron or plate washers when bearing on wood and heavy cut washers when bearing on steel. (g) Determination of allowable stresses for design methods based on test results. (1) Design shear values. Design seismic in-plane shear stresses greater than permitted in Table G shall be substantiated by tests performed as specified in subsections (e) (3) and (4) of section 8-2006. Design stresses shall be related to test results obtained as noted in Table G. Intermediate values below the maximum may be interpolated. TABLE G ALLOWABLE SHEAR STRESS FOR TESTED UNREINFORCED MASONRY WALLS Eighty per cent by test results in psi not less than Average test results cores in psi Seismic in-plane shear based on gross area 30 plus axial stress 20 3 psi(1) 40 plus axial stress 26.7 4 psi(1) 50 plus axial stress 33.3 5 psi(1) 100 plus axial stress or more 67 or more 10 psi maximum(1) 21 ORDINANCE NS-2182 PAGE 22 Footnotes: (1) Allowable shear stress may be increased by addition of ten (10) per cent of the axial stress due to the weight of the wall directly above. Design compression and tension values. Design compressive stresses of analysis specified in this section shall be one hundred (100) psi. Design tension values for unreinforced masonry shall be assumed equal to zero. (h) Testing of rod anchors. Five (5) per cent of the existing rod anchors utilized as all or part of required wall anchors shall be tested in pullout by an approved testing laboratory. The minimum number tested shall be four (4) per floor, with two (2) tests at walls with joists framing into the wall and two (2) tests at walls with joists parallel to the wall. The test apparatus shall be supported on the masonry wall at a minimum distance of the wall thickness from the anchor tested. The rod anchor shall be given a preload of three hundred (300) pounds prior to establishing a datum for recording elongation. The tension test load reported shall be recorded at one-eighth (1/8) inch relative movement of the anchor and the adjacent masonry surface. Results of all tests shall be reported. The allowable resistance value of existing anchors shall be forty (40) per cent of the average of the reported test loads. (i) Tests for wall anchorage. 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 twenty (20) per cent of the average of the ultimate loads.
