Cathcart Residence—Truss Repair 2 <br /> December 21, 2009 <br /> 2.3 The bottom chord of the truss is also built-up out of four separate pieces of lumber that <br /> are fastened togetlier. The exterior pieces consist of 2 x 8 members with the interior <br /> pieces 2 x4 members. <br /> 2.4 The north bearing end of tlle damaged truss had a portion of the exterior top and bottom <br /> chord members removed revealing the interior members of the chords and a gap of <br /> approximately 5/8"between them. <br /> 2.5 A gap of approximately 1/8"was also observed at the location �vhere the northern most <br /> vertical and diagonal web intersects with the top chord. <br /> 3.0 ANALYSIS AND RECONINIENDATIOtiS <br /> 3.i The chord members at the north end of the built-up truss are not structurally tied together <br /> where the gap exists between the members. These chords should be tied together in <br /> order for the components to structurally function as a truss. It is recommended that the <br /> north bearing end of the truss should be repaired per the attached North Bearing End <br /> Detail and General Notes. <br /> 3.2 It is recommended to compress the exterior members of the chords and webs tight at tlle <br /> location where the vertical and diagonal web members have displaced from the top <br /> chord. This should be done by installing 5/16"diameter x 3 1/8"long RSS structural <br /> screws spaced 2"o.c. at a 30 degree angle with the web member through the exterior <br /> pieces of the web members and into the top chord lumber. Refer also to the Top <br /> Chord/Web Intersection detail and General Notes. <br /> This report is prepared based on observations and revie�v of the material available as of this date. <br /> Our opinions may be revised based on the availability of additional data. <br /> The conclusions and recommendation contained herein represent our professional opinions. <br /> These opinions were arrived in accordance with accepted engineering practices at this time and <br /> location.
