STRUCTURAL GENERAL NOTES _____________________________________________________________________________________________ DESIGN LOADS: 2012 International Building Code (IBC), except as noted Live Loads: Floor 40 psf ______________________________________________________________________________________________ STRUCTURAL WOOD & TIMBER: In-Grade Base Values have been used for design. Fasteners for use with treated wood shall comply with IRC Section 2304.9.5 - '06/'09 IBC. Conventional light framing shall comply with IBC Section 2308. All beams and trusses shall be braced against rotation at points of bearing. Except as noted otherwise, minimum nailing shall be provided as specified in IBC Table 2304.9.1 "Fastening Schedule." Metal framing anchors shown or required, shall be Simpson Strong-Tie or equal Code approved connectors and installed with the number and type of nails recommended by the manufacturer to develop the maximum rated capacity. Note that heavy-duty hangers and skewed hangers may not be stocked locally and require special order from the factory. Lead holes for lag screws shall be 40%-70% of the shank diameter at the threaded section and equal to the shank diameter at the unthreaded section per NDS section 11.1.3. Connector bolts and Lag Screws shall conform to ANSI/ASME B18.2.1 and ASTM SAE J429 Grade 1. Nails and Spikes shall conform to ASTM F1667. Wood Screws shall conform to ANSI/ASME B18.6.1. _____________________________________________________________________________________________ PLANT FABRICATED / PRE-ENGINEERED WOOD FRAMING: I-series roof and floor joists shall be manufactured by iLevel Trus Joist with structural wood flanges and webs designed for structural capacities and design provisions according to ASTM D 5055. Substitution of equivalent series by other manufaturer is acceptable with engineer approval. I-series roof and floor joists shall be installed per the manufacturer's recommendations. Do not cut or notch chords in any manner. Holes in webs shall not exceed manufacturer's published limit criteria. Members noted as LVL (Laminated Veneer Lumber) on plan shall be 1-3/4 wide x depth indicated, plant-fabricated, and have the following minimum allowable design values: F /b = 2600 psi F /v = 285 psi F /c|| = 2460 psi F /c- = 750 psi E = 1900 ksi Members noted as PSL (Parallel Strand Lumber) on plan shall be plant-fabricated and have the following minimum allowable design values: F /b = 2900 psi F /v = 290 psi F /c|| = 2900 psi F /c- = 750 psi E = 2000 ksi Members noted as LSL (Laminated Strand Lumber) on plan shall be plant-fabricated and have the following minimum allowable design values: F /b = 1700 psi F /v = 400 psi F /c|| = 1400 psi F /c- = 680 psi E = 1300 ksi Bridging and blocking shall be installed according to the fabricator's requirements. _____________________________________________________________________________________________ FIELD VERIFICATION OF EXISTING CONDITIONS: The General Contractor shall thoroughly inspect and survey the existing structure to verify conditions that affect the work shown on the drawings. The General Contractor shall report any variations or discrepancies to the Architect and Structural Engineer before proceeding. _____________________________________________________________________________________________ STRUCTURAL ERECTION AND BRACING REQUIREMENTS: The Structural Drawings illustrate and describe the completed structure with elements in their final positions, properly supported, connected, and/or braced. The Structural Drawings illustrate typical and representative details to assist the General Contractor. Details shown apply at all similar conditions unless otherwise indicated. Although due diligence has been applied to make the drawings as complete as possible, not every detail is illustrated and not every exceptional condition is addressed. All proprietary connections and elements shall be installed in accordance with the manufacturers' recommendations. All work shall be accomplished in a workmanlike manner and in accordance with the applicable codes and local ordinances. The General Contractor is responsible for coordination of all work, including layout and dimension verification, materials coordination, shop drawing review, and the work of subcontractors. Any discrepancies or omissions discovered in the course of the work shall be immediately reported to the Architect and Structural Engineer for resolution. Continuation of work without notification of discrepancies relieves the Architect and Structural Engineer from all consequences. Unless otherwise specifically indicated, the Structural Drawings do not describe methods of construction. The General Contractor, in the proper sequence, shall perform or supervise all work necessary to achieve the final completed structure, and to protect the structure, workmen, and others during construction. Such work shall include, but not be limited to temporary bracing, shoring for construction equipment, shoring for excavation, formwork, scaffolding, safety devices and programs of all kinds, support and bracing for cranes and other erection equipment. Temporary bracing shall remain in place until all floors, walls, roofs and any other supporting elements are in place. The Architect and Structural Engineer bear no responsibility for the above items, and observation visits to the site do not in any way include inspections of these items. These plans have been engineered for construction at one specific building site. Builder assumes ALL responsibility for use of these plans at ANY OTHER building site. Plans shall not be used for construction at any other building site without specific review by the engineer. _____________________________________________________________________________________________ NORTH EXISTING 1 1/2" NON- STRUCTURAL TOPPING ON 3/4" PLYWOOD SUB-FLOOR EXISTING 2x4 EXTERIOR WOOD STUD WALL EXISTING 6x12 TIMBER BEAM EXISTING 2x4 EXTERIOR WOOD STUD WALL (2) 11 1/4" LVL BEAM U410 w/ 16d SINKERS INTO TIMBER BEAM EXISTING 1 1/2" NON- STRUCTURAL TOPPING ON 3/4" PLYWOOD SUB-FLOOR (2) 11 1/4" LVL BEAM w/ (3) ROWS OF 0.131"Øx3" NAILS @ 12" EXISING 2x12 FLOOR JOISTS LUS210 SHORING BY CONTRACTOR NEW OPENING REMOVE EXISTING FLOOR ASSEMBLY 18'-5 1/2" EXISTING 10" REINFORCED CONCRETE STRUCTURAL SLAB EXISTING 8" CMU FOUNDATION WALL BELOW NEW SPIRAL STAIR CENTER COLUMN 8'-0" 1 S1 EXISTING #5 @ 12", TOP & BOTTOM EXISTING #5 @ 17", TEMP REINFORCEMENT * EXISTING 10" STRUCTURAL CONCRETE SLAB REINFORCEMENT IS BASED ON THE ORIGINAL CONSTRUCTION DOCUMENTS AND HAS NOT BEEN FIELD VERIFIED.
