Roof Framing Bundle: E-book + Roof Framing Designer (NSCP 2015)
Learn it in the book, check it in the sheet. This bundle pairs the e-book Roof Framing Design Made Clear (NSCP 2015) with its companion spreadsheet, the Roof Framing Designer (NSCP 2015).
E-book (175-page PDF): a step-by-step guide to the design of steel roofs per NSCP 2015, from the roofing sheets down to the anchor rods: loads, cold-formed purlins, sag rods, the Fink truss and its members, bracing, joints and the truss supports, in 15 chapters. About 33 worked examples, practice problems with answers at the end of each chapter, a quick-reference chapter, a full notation list and a blank calculation template you can print. Every number in the worked examples and in the answers is recomputed by a second calculation written from the printed code.
Spreadsheet (Excel workbook): designs the roof framing of one steel gable roof on angle trusses by NSCP 2015 (7th edition, SI) in one linked workbook: the roofing-sheet screws, the cold-formed purlins and sag rods, the steel truss analysis and its members, the joints, and the supports with their anchor rods. Wind comes from the roof geometry (MWFRS and components and cladding by zone). All checks are listed in a 113-row Design Check Summary with demand, capacity, ratio and status, and every result is a visible Excel formula. The sample calculation (74 pages, previewed with View sample on the Roof Framing Designer card) is roof R-1 of a 12 x 24 m shop in Metro Manila, with the basic wind speed read from the wind map and to be confirmed for a real site. The truss analysis was compared with an independent ETABS 22 model: 3,213 member forces agree to rounding.
Bought separately: PHP 1,499 + PHP 1,499 = PHP 2,998. The bundle is PHP 2,789 and saves you PHP 209 (about 7%).
For students, board-exam reviewees and young engineers. Neither the book nor the spreadsheet covers portal frames or standing-seam roofs. Each copy is made out to the buyer's name. One licence per reader for the book, and per engineer or office for the spreadsheet.
