2 Page 2 of 11 ESR General: Anchors described in this report are assigned allowable tension and shear loads for designs based on allowable stress design (working stress design). Use of the anchors to resist vibratory and moving loads, such as those produced by reciprocating engines, cranes and vehicles, is beyond the scope of this report Design of Anchors in Normal-weight Concrete: Allowable tension and shear loads for installation in normalweight concrete are noted in Tables 3 through 6. Spacing and edge distance requirements are noted in Tables 1 through 6. Allowable load reduction factors noted in Table 2 are applicable only to the allowable loads shown in Tables 3 and 4. For installations in normal-weight concrete, anchors are recognized to resist dead-, live-, wind-, and earthquake-load applications. Allowable loads may be increased by 33 1 / 3 percent when using the alternate basic load combinations in accordance with Section of the IBC or Section of the UBC, for wind or earthquake loading conditions. Alternatively, the load combinations in IBC Section may be multiplied by a factor of Allowable loads for anchors installed in normal-weight concrete subjected to combined shear and tension forces shall be determined by the following equation: P s P t 5/3 V + 5/3 s V t # 1.0 where: P s = Applied service tension load. P t = Allowable service tension load. V s = Applied service shear load. V t = Allowable service shear load Design of Anchors in the Top or Bottom of Structural Sand-lightweight Concrete Filled Metal-deck Assemblies: Allowable tension and shear loads, and spacing and edge distance requirements, for anchors installed in the top or bottom of structural sand-lightweight concrete filled metal-deck assemblies are noted in Table 7. Refer to Figure 2 for required assembly details. Anchors installed in the top of structural sand-lightweight concrete and metal-deck assemblies may resist wind or earthquake loads. Allowable tension and shear loads may be increased by 33 1 / 3 percent when using the alternate basic load combinations in accordance with Section of the IBC or Section of the UBC, for wind or earthquake loading conditions. Alternatively, the load combinations in IBC Section may be multiplied by a factor of Anchors installed in the bottom of structural sandlightweight concrete and metal-deck assemblies may resist wind or earthquake loads: Allowable tension loads for bottom deck installations may be increased by 33 1 / 3 percent when using the alternate basic load combinations in accordance with Section of the IBC or Section of the UBC, for wind or earthquake loading conditions. Alternatively, the load combinations in IBC Section may be multiplied by a factor of Allowable shear loads for bottom deck installations shall not be increased when using the alternate basic load combinations in accordance with Section of the IBC or Section of the UBC, for wind or earthquake loading conditions. Allowable loads for anchors installed into the top or bottom of structural sand-lightweight concrete filled metal-deck assemblies subjected to combined shear and tension forces shall be determined by the following equation: P s P t V + s V t # 1.0 where: P s = Applied service tension load. P t = Allowable service tension load. V s = Applied service shear load. V t = Allowable service shear load Design of Anchors in Fully Grouted CMU Masonry Walls: Allowable tension and shear loads for anchors installed in the face of fully grouted CMU masonry walls are noted in Table 8A for structures complying with the IBC or IRC, and Table 8B for structures complying with the UBC. The allowable tension and shear loads are for anchors installed in the grouted cells, the center web of CMU units, and horizontal mortared bed joints of fully grouted CMU masonry wall construction. Allowable loads for anchors installed in the vertical head joint or the end flanges of the CMU units are outside the scope of this report. Edge and end distances, and spacing requirements for anchors installed in the face of fully grouted CMU masonry walls, as shown in Figure 3, are noted in Tables 8A and 8B. Allowable load reduction factors for anchors installed at reduced edge and end distances, and reduced spacing, are noted in Tables 9 and 10. Allowable tension and shear loads for 1 / 2 -inch and 5 / 8 -inch (12.7 mm and 15.9 mm) anchors installed in the top of fully grouted concrete masonry walls (CMU grouted cores and CMU webs), are noted in Table 11A for anchors installed in structures complying with the IBC or IRC, and Table 11B for anchors installed in structures complying with the UBC. When using the alternate basic load combinations in IBC Section or UBC Section that include wind or earthquake loads, the allowable shear and tension loads for anchors installed in the face and the top in fully grouted CMU masonry walls may be increased by 33 1 / 3 percent. Alternatively, the load combinations in IBC Section may be multiplied by a factor of Allowable loads for anchors installed in the face of fully grouted CMU masonry walls subjected to combined shear and tension forces shall be determined by the following equation: P s P t V + s V t # 1.0 where: P s = Applied service tension load. P t = Allowable service tension load. V s = Applied service shear load. V t = Allowable service shear load. 4.0 INSTALLATION 4.1 General: Titen HD screw anchors shall be installed by drilling a pilot hole into the substrate using a handheld electro-pneumatic rotary hammer drill with a carbide-tipped drill bit conforming to ANSI B The pilot hole shall have the same diameter as the nominal diameter of the anchor. The hole is drilled to the specified embedment depth plus 1 / 2 inch (12.7 mm). Dust and debris in the hole shall be removed by using

Anchors installed in the mortared head joint are outside the scope of this report 4.2 Installation with Inspection (When Required): Continuous special inspection shall be provided when required by the tables in this evaluation report. inspection under the IBC and IRC shall conform to IBC Section 1704; under the UBC, special inspection shall be in accordance with UBC Section For fasteners installed with special inspection, the following items, as applicable, shall be inspected: fastener type and dimensions; concrete type and concrete compressive strength (for anchors installed in concrete); masonry unit type and compliance with ASTM C 90; grout and mortar compressive strengths, and (when required) masonry prism compressive strength; drill bit size and compliance with ANSI B ; and fastener embedment, spacing, and edge (and end) distances. The special inspector shall inspect and verify that anchor installation complies with this evaluation report and Simpson Strong-Tie Company s published installation instructions. 5.0 CONDITIONS OF USE The Titen HD Screw Anchors described in this report comply with, or are suitable alternatives to what is specified in, the codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 Anchors are identified and installed in accordance with this report and the manufacturer s published installation instructions. 5.2 Anchors installed in normal-weight concrete to resist dead, live, wind and earthquake load applications shall be in accordance with Section Anchors installed into the top or bottom of structural sand-lightweight concrete filled metal-deck assemblies to resist dead, live, wind and earthquake load applications shall be in accordance with Section Anchors installed in the face or the top of fully grouted CMU masonry walls to resist dead, live, wind, and earthquake load applications shall be in accordance with Section Since an ICC-ES acceptance criteria for evaluating data to determine the performance of anchors subjected to fatigue or shock loading is unavailable at this time, the use of these anchors under these conditions is beyond the scope of this report. 5.6 Anchors are not permitted for use in conjunction with fire-resistive construction. Exceptions would be: Anchors resist wind or seismic loading only. For other than wind or seismic loading, special consideration is given to fire exposure conditions. 5.7 Since an ICC-ES acceptance criteria for evaluating the performance of screw anchors in cracked concrete is unavailable at this time, the use of anchors is limited to installation in uncracked concrete. Cracking occurs when f t > f r due to service loads or deformations. 5.8 Anchors are installed in substrates in holes predrilled with carbide-tipped masonry drill bits complying with ANSI B , and having the same diameter as the nominal diameter of the anchor. 5.9 Calculations demonstrating that the applied loads are less than the allowable loads described in this report, shall be submitted to the building official.
