202024The combination of seismic and vehicle live loadings on bridges is an important design consideration. There are wellestablished design provisions for how the individual loadings affect bridge response structural components that carry vertical live loads are designed to remain well within the linearelastic range while lateral load carrying

2014725seismic evaluation of truss bridges. Level 3evaluation is an indepth seismic evaluation. This is usually employed for bridges that cannot be conservatively assessed by a Level 2 evaluation and for bridges that serve as very critical links in the transportation system. Global and local 3D finite element models are developed to compute the
Integral abutment bridges IABs have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges the

Adverse effects found in this study were generally within 10 of the nolive load case. Until further studies are complete it appears generally conservative to ignore the dynamic effect of live load on the seismic response of ordinary bridges.
Emphasis on deflection live load distribution dynamic load allowance and multiple presence To evaluate the existing design provisions of AASHTO LRFD BDS and the AREMA manual for light rail train load To propose design information about live load effects for bridges carrying light rail trains or carrying light rail trains and highway
During a strong seismic event a monorail train is assumed to be standing on the trackgirder of the monorail bridge. It is noted that considering monorail trains as additional mass in numerical modeling may overestimate live load effects on seismic performance of monorail bridges.

Suspension bridges are complex 3D structures that can exhibit a large number of closely spaced coupled modes of vibration. The large number of closely spaced modes spatially different ground motion characteristics and the potential for nonlinear behaviour complicate the seismic response of suspension bridges.
2. Wind load on live load Wind pressure on vehicles shall be represented by a uniform load of 0.100 kipsft 1.46 kNm applied at right angles to the longitudinal axis of the structure and 6.0 ft 1.85 m above the deck to represent the wind load on vehicles. 3.

Integral abutment bridges IABs in Illinois can be subjected to a wide range of seismic haard particularly due to the proximity of the southern region of the state to the New Madrid Seismic Zone. The lack of expansion joints in IABs places a greater emphasis on the interaction between abutment piles and surrounding soil during seismic events.

Harstead Hardesty Hanover LLP Consulting Engineer New York NY Park Ridge NJ ABSTRACT The operatability and stability of movable railroad bridges depends on the integrity of machinery. This holds true for all positions of the movable span.
