Research Solutions: Assessing the Impact of New Legalized Axle Loads on Bridges, TR-798/RE22009, 2025
No full textLive load field tests of bridges were carried out using certain implements of husbandry (IoH) to observe the transverse load distribution and the dynamic impacts. A finite element (FE) analysis of the field-tested bridges was performed. The strain data from the FE analysis were validated with the field test data to establish an FE analysis method for a parametric study. This parametric study was performed to observe the influence of various bridge parameters on the load distribution factors. Observation of the load distribution factors from the parametric study shows that the load distribution factor equations prescribed in the AASHTO LRFD (2020) capture the distribution for these IoH loads. Live load factors for this load type for prestressed concrete (PC) bridges and steel girder bridges were found through a calibration process using reliability theory, which involves the selection of a target safety index. The live load factor for each bridge type was calculated for the Strength I and II limit states. An Iowa-specific legally loaded vehicle (Terragator Max) was established using a conservative axle configuration and axle loads of 25 kips. Calibration of the live load factors yielded the following key findings: • An update to the AASHTO load and resistance factors (LRFs) is not needed for existing terragator loads as long as the axle loads comply with the legal load limit of 25 kips. • When a target safety index of 3.5 is considered, the current live load factor of 1.75 for Strength I should be increased to 1.90 if husbandry vehicles of a configuration similar to that of Terragator Max are manufactured. • When a target safety index of 2.0 is considered, the same case does not suggest an update to the AASHTO live load factor. • An update to the AASHTO Strength II LRFs is not required. • The dead load factors were found to be lower than the current AASHTO-prescribed values. Therefore an update to the AASHTO LRFs is not required. • The resistance factors were found to be close to the AASHTO resistance factors for moment and shear
