Horizontal forces Sample Clauses

The "Horizontal forces" clause defines the requirements and considerations for managing lateral loads that act on a structure, such as wind or seismic forces. It typically outlines how these forces should be calculated, distributed, and resisted by the building's structural system, specifying design standards or load combinations to be used. By addressing horizontal forces, this clause ensures the stability and safety of the structure under non-vertical loads, preventing structural failure due to sideways movement or collapse.
Horizontal forces. For mechanical coupling devices and components not designed to support imposed vertical loads, the value is: ܦൌ்݃כோ kN ்ାோ For mechanical coupling devices and components for center axle trailers as defined in 2.13, the value is: ܦ ൌ்݃כ஼ kN ஼ ்ା஼ For fifth wheel couplings of Class G, fifth wheel coupling pins of Class H and mounting plates of Class J, as defined in paragraph 2.6., the value is: ܦൌ݃଴Ǥ଺כ்כோ kN ்ାோି௎ where: T is the technically permissible maximum mass of the towing vehicle, in tonnes. Where relevant, this includes the vertical load imposed by a center axle trailer1. R is the technically permissible maximum mass, in tonnes, of a trailer with drawbar free to move in a vertical plane, or of a semitrailer1. C is the mass, in tonnes, transmitted to the ground by the axle or axles of the center axle trailer, as defined in paragraph 2.13., when coupled to the towing vehicle and loaded to the technically permissible maximum mass1. For Category O1 and O2 center axle trailers2 the technically permissible maximum mass will be that declared by the manufacturer of the towing vehicle. Towable mass: R or C (as applicable) 2.2. Vertical forces from center axle trailer The vertical force imposed on the coupling by the center axle trailer of technically permissible maximum mass greater than 3.5 tonnes is: 1 The mass T and R and the technically permissible maximum mass, may be greater than the permissible maximum mass prescribed by national legislation. 2 See definitions in UN Regulation No. 13 annexed to the 1958 Agreement the Adoption of Harmonized Technical United Nations Regulations for Wheeled Vehicles, Equipment and Parts which can be Fitted and/or be Used on Wheeled Vehicles and the Conditions for Reciprocal Recognition of Approvals Granted on the Basis of these United Nations Regulations.

  • Loop Provisioning Involving Integrated Digital Loop Carriers 2.6.1 Where Freedom has requested an Unbundled Loop and BellSouth uses IDLC systems to provide the local service to the End User and BellSouth has a suitable alternate facility available, BellSouth will make such alternative facilities available to Freedom. If a suitable alternative facility is not available, then to the extent it is technically feasible, BellSouth will implement one of the following alternative arrangements for Freedom (e.g. hairpinning): 1. Roll the circuit(s) from the IDLC to any spare copper that exists to the customer premises. 2. Roll the circuit(s) from the IDLC to an existing DLC that is not integrated. 3. If capacity exists, provide "side-door" porting through the switch. 4. If capacity exists, provide "Digital Access Cross Connect System (DACS)- door" porting (if the IDLC routes through a DACS prior to integration into the switch). 2.6.2 Arrangements 3 and 4 above require the use of a designed circuit. Therefore, non- designed Loops such as the SL1 voice grade and UCL-ND may not be ordered in these cases. 2.6.3 If no alternate facility is available, and upon request from Freedom, and if agreed to by both Parties, BellSouth may utilize its Special Construction (SC) process to determine the additional costs required to provision facilities. Freedom will then have the option of paying the one-time SC rates to place the Loop.
