Hl 93 Moment Tables

Calculator offers options for HL-93 , KGM45, and a manual selection of live load model.

The live load calculator aims to find maximum live load moment under a choice of truck models.

Truck Loads consist of P1, P2 and P3 axle loads, and wllu uniform load per lane.

28/01/2018 HL-93 Design Tandem consist of twin axles spaced 4# (1.

2m) apart, weight of each axle is 25kip (110 kN).

The distance between the tyres in an axle is 6# (1.


HL-93 Design Tandem AASHTO.

To obtain maximum negative moments , a pair of tandems should be considered, spaced at 8.

0m to 12.

0m along with design lane load to produce worse hogging.

com Thanks & #, A system of lane loads was created to provide a simpler method of calculating moments and shears rather than using concentrated wheel loads shown in Figures 1 and 2.

which states that the tables were created using the AASHTO HL 93 live load without the lane load as permitted by AASHTO.

Created Date: 6/23/2009 1:49:39 PM, 06/06/2014 This paper proposes to derive an equation for determining the correct truck offset to produce maximum moment using HL-93 loading on simple spans greater than 40 ft (12.

192 m).

The scope of this paper does not include the tandem vehicle, because it does not govern spans greater than 40 ft (12.

192 m) in length.

With the institution of AASHTO HL-93 loading, calculating the maximum live-load moment on simple spans became more complex than it had been previously.

In the past, to find the maximum live-load moment from the HS-20 design truck, the middle axle was offset from midspan by 0.

711 m (2 ft 4 in.

), and the moment under that axle was the maximum.

levels as rating factors of the AASHTO HL-93 live load.

Once overload permitting and bridge posting policies are revised to accommodate LRFR, load ratings using the LFD and ASD methods will be discontinued.

The NYSDOT Bridge Manual supplements both the LRFD Specifications and the Standard Specifications for Highway Bridges.
