“…In this study, free vibration wind tunnel tests were used to assess the heaving vortex-induced vibration (VIV) of a box-girder bridge for non grid and grid-like handrail situations. This work also offers fresh perspectives on the optimisation of aerodynamically sound handrail configurations and the simplification of handrail models for assessing the aerodynamics of a bridge girder during the design phase [12]. This paper gives a brief idea of IABs.…”

From the past evaluation and trend in bridge engineering Integral abutment bridges are gaining more popularity than conventional bridges. Kalkaji Flyover Delhi is one of the recent examples of five span continuous deck IAB. Girders are directly joined with abutment/piers without any bearings. These girders play most important role in dead load of bridge. The present study is the analytical investigation of precast concrete girder used in IAB undergone to different loads. The software used for the analysis is Csi Bridge in which a bridge of width 22 metres having the slab thickness 0.3 metres is analysed. There are five longitudinal girders (I beam of 575 mm width and 250 mm thickness) provided across the bridge’s width spaced at 2.54 metres centre to centre from each other. The girder is subjected to dead load, thermal load, backfilling, dead load with thermal load and combination of loads. Through the finite element modelling, values for different parameters for different load cases are computed. The results of this study are showing that there is no effect of backfilling for hogging but on the other hand for sagging moment the value is 12.35 kN-m. Maximum value of bending moment is due to combination of loads. Stresses developed in deck slab at the bottom are highest due to thermal loads and lowest due to backfilling. On the top of deck the stress values are highest for combination of loads. Deadload can be reduced if the Steel Plate girder is used that’s the practical implementation in integral abutment bridges.

The vibration acceleration response and excellent frequency generated by pedestrian’s walking type of the steel composite wooden bridge were measured and analyzed. Based on the modified Reiher-Meister vibration curve, vibration influence evaluation on the structural perspectives of the pedestrian bridge was performed. The pedestrian’s walking types were divided into walking, running, rolling, and shaking, and eight experimental cases were set up by combining them with the number of users and moving direction. A total of 37 measurements were made. To evaluate the vibration serviceability of pedestrian bridges, the pedestrian’s walking type must be considered, and a standardized study on the pedestrian’s walking type will be necessary in the future.
