Common use of STRUCTURAL COMPONENTS Clause in Contracts

STRUCTURAL COMPONENTS. 1. Live loads: Entire office floor loading shall provide 100 pounds per square foot (minimum) live loads. Limit floor deflection to L/360. Do not reduce live load for horizontal framing members/columns or load bearing walls supporting top floor or roof. 2. Where required by the Request for Proposal (RFP), Program, or State Agency Supplementary Standards: provide special floor loading requirements for computer room loads, special equipment loads and storage loads. 3. Where required by the Request for Proposal (RFP), Program, or State Agency Supplementary Standards: Design 1 bay per floor for high density storage systems. 4. Non‐structural, rigid partitions shall be adequately supported so as not to become load bearing. 5. Masonry walls are to be isolated from floor above by a gap and restrained by either an intermittent or continuous steel angle on both sides at top of wall or steel straps extending in the wall grout. 6. Metal stud partitions do not require in‐plane lateral isolation from structure if the design story drift ratio multiplied by 3(R/8) is less than 0.0025. 7. Top of stud in full height walls is to be separated from the track. Use deflection tracks. 8. Building expansion is to be carried through crossing partitions. 9. Design Procedures for New Construction: a) Load Resistance Factor Design (LRFD): Use for small or large building structures. b) Allowable Stress Design (ASD): Use for small building structures only. 10. Progressive Collapse for New Construction: a) Building is not to be subject to progressive collapse as defined by the building code. b) Beam or slab failure shall not affect system below or in adjacent bays. c) Column failure shall affect only the bays supported by that column 11. Drift for new construction: Lateral deflection of building under lateral load is to be limited to wind and earthquake requirements. Wind induced motion and sway must also be limited. Design roof massing and roof structure to prevent excessive drift and potential collapse. 12. Transient vibration induced by passing traffic or foot fall is to be minimized. 13. Corrosion Protection for new construction: Steel exposed to elements is to have a protective coating. For small isolated steel elements use either hot dipped galvanized zinc coating or coal tar epoxy. For larger exposed steel elements use a 2‐coat system: a) Coat 1: organic zinc rich urethane or epoxy primer shop applied over blast cleaned surfaces. b) Coat 2: field applied finish coat. 14. For concrete in new construction parking structures use corrosion inhibiting additives and cathodic protection or epoxy coated reinforcing bars and surface sealers. 15. Attachment of new exterior cladding: a) Provide connections and joints that provide movement between stories b) Connections to have sufficient ductility and rotation capacity to preclude brittle failure in connection welds or concrete fractures c) Concrete inserts are to be attached to or hooked around reinforcing steel d) Positively anchor window frames to resist lateral loads e) Provide clearance and flexible mountings at window frames to permit thermal movement 16. Attachment of new partitions: a) Adequately support non‐structural, rigid partitions so as not to become load bearing b) Isolate masonry walls from floor above by a gap and restrain by either an intermittent or continuous steel angle on both sides at top of wall or steel straps extending in the wall grout c) Metal stud partitions do not require in‐plane lateral isolation from structure if the design story drift ratio multiplied by 3(R/8) is less than 0.0025. d) Top of stud in full height walls is to be separated from the track. Use deflection tracks.
