PPT-DESIGN OF TRUSS ROOF Chapter 7

University of Engineering amp Technology Taxila 1 Prof Dr Z A Siddiqi LOADS ON TRUSS ROOF All the gravity or vertical loads acting on the building trusses are first calculated in terms of the loads acting per one square meter of the horizontally projected area plan area having the units kgm. http://www.mlsroofing.com MLS Roofing and Construction Company can handle everything from a additions to new roofs, leaks, shingles, siding and gutters to repairs using the highest quality products available at a very competitive price. A body being squeezed. Forces. Compression. Tension. A body being stretched. Truss. A truss is composed of slender members joined together at their end points.. They are usually joined by welds or gusset plates.. Calculating a Roof Pitch. Architecture I. What is the Roof Pitch?. The roof's . Pitch is what . is called "slope" in . geometry. Pitch = Rise/Run. Run = ½ Span. Roof Pitch to Degree Equivalents. This drawing demonstrates how many degrees rise for each pitch of a typical roof. Look at the column labeled pitch, then look under degrees to get the corresponding amount of degrees. . Overview. Introduction. Fire retardant treatments (FRT) were developed to be applied to building materials, such as dimension lumber (FRTW) and plywood, to reduce the ability of the wood to fuel a fire. . Objectives. To introduce a truss-structure system. To define truss. To demonstrate the types of trusses . 6 - . 3. Introduction. For the equilibrium of structures . which are . made . up . of several connected parts, the . A body being squeezed. Forces. Compression. Tension. A body being stretched. Truss.

If it\'s been a while since you last had your roof inspected, now is the perfect time to make an appointment. Roof inspections are important for preserving the structural integrity of your home, and they can save you thousands upon thousands of dollars in repairs.

Analysis normally begins at a joint where at least one force is known and not more than two forces are unknown for plane trusses (or not more than three forces are unknown for space trusses).
