A study on future design live loadings (NZTA research report 539) recommended that new evaluation loadings be based on multiples of SM1600 loading from AS 5100.2 or alternatively on higher multiples of HN loading. However, we found that neither option could provide consistent fits to effects of conforming vehicles at all span lengths. For HN loadings there are significant shortfalls for negative moment effects in continuous spans and scaled down SM1600 design loadings have a generally poor fit to single vehicle effects. A goal for the development was to achieve closer harmonisation between the Bridge manual and AS 5100 if possible. Adopting the nominated rating vehicle approach from AS 5100.7 provided the opportunity to realise that goal. The paper shows that maximum load effects for the full ranges of conforming HPMV and general access vehicles allowed by regulations can be fully represented by small sets of conforming vehicles. The new loadings provide dependable representation of the effects of conforming vehicles, without substantial overall increases across the full range of span lengths except where the significant shortfall in continuous span effects has been addressed.]]> Thu, 07 Dec 2023 14:55:12 GMT https://trid.trb.org/View/2306877 Vehicle induced dynamic effects on steel-concrete composite bridges: a comparative study in field testing and finite element analysis https://trid.trb.org/View/2306875 Thu, 07 Dec 2023 14:55:10 GMT https://trid.trb.org/View/2306875 Innovative solutions to old problems: sustainable upgrade of existing infrastructure: strengthening and rehabilitation of the LH Ford Bridge https://trid.trb.org/View/2306864 Thu, 07 Dec 2023 14:54:59 GMT https://trid.trb.org/View/2306864 Heavy vehicle impacts on bridges: case studies in risk assessment https://trid.trb.org/View/2306856 Thu, 07 Dec 2023 14:54:51 GMT https://trid.trb.org/View/2306856 Fatigue evaluation of ageing steel railway bridges on current rail network in Victoria https://trid.trb.org/View/2306851 Thu, 07 Dec 2023 14:54:46 GMT https://trid.trb.org/View/2306851 Extending the life of heritage bridges using advanced finite element modelling and analysis https://trid.trb.org/View/2306849 Thu, 07 Dec 2023 14:54:44 GMT https://trid.trb.org/View/2306849 Existing ballasted rail bridge assessment: benefits of a Rail Structure Interaction analysis https://trid.trb.org/View/2306848 Thu, 07 Dec 2023 14:54:43 GMT https://trid.trb.org/View/2306848 Captain Cook Bridge bearing replacement and halving joint strengthening works https://trid.trb.org/View/2306770 Thu, 07 Dec 2023 14:53:27 GMT https://trid.trb.org/View/2306770 Strengthening bridges of the West Gate Tunnel Project https://trid.trb.org/View/2306769 Thu, 07 Dec 2023 14:53:26 GMT https://trid.trb.org/View/2306769 Bond and re-anchoring tests of post-tensioned steel tendon in case of strand failure inside cement grouting with voids https://trid.trb.org/View/1925723 Thu, 10 Mar 2022 08:32:38 GMT https://trid.trb.org/View/1925723 Reliability evaluation of concrete-filled steel tube arch bridge based on DBN-PSOSA hybrid algorithm https://trid.trb.org/View/1925722 Thu, 10 Mar 2022 08:32:38 GMT https://trid.trb.org/View/1925722 Full-scale tests on bridge kerbs subjected to horizontal actions https://trid.trb.org/View/1909593 Mon, 07 Feb 2022 14:17:55 GMT https://trid.trb.org/View/1909593 Identification of modal parameters based on moving force excitation https://trid.trb.org/View/1890711 Tue, 09 Nov 2021 09:24:02 GMT https://trid.trb.org/View/1890711 Highway bridges in fire: characterisation of fire loading and structural behaviour https://trid.trb.org/View/1736479 Tue, 01 Sep 2020 14:50:13 GMT https://trid.trb.org/View/1736479 9th Australian Small Bridges Conference, Surfers Paradise, Queensland, 1-2 April 2019 https://trid.trb.org/View/1647542 Mon, 26 Aug 2019 11:34:42 GMT https://trid.trb.org/View/1647542
