“…He gave the finite element approach for geometric nonlinear aerostatic analyses of self-anchored cable stayed bridge. The construction of a cable stayed bridge achieving the desired strength and serviceability, meeting all the design criteria along with the minimum cost is a challenging task [8][9] In the recent studies some studies gave a practical view on Static Analysis of Cable Stayed Bridges. The study discusses about how cable stayed bridges has helped designers to control and adjust the forces of different elements of bridges as when the load is fixed the beam forces can be changed by adjusting cable forces which allows designer to control beam forces of the bridge, these structures are also known as Active Structures [10][11].…”

Cable stayed bridges are known for their good stability, It has been the most favorable use of structural design, for comparatively low designing and maintenance costs, and for effective structural characteristics. Therefore, this type of bridges are gaining popularity and are generally selected for long spans when compared to suspension bridges. A cable stayed bridge comprises of pylons with cables withstanding the weight of deck. There are different types of pylons i.e. ; H-type pylon, A-type pylon, inverted Y-type pylon, and diamond shaped pylon. In this paper the bridge design, model, and analyses for these different types of pylons is done using STAAD Pro. The comparison for three cases are done on the basis of shear force and bending moment in terms of self weight to obtain the most efficient type of pylon design. The results thus obtained are useful in limiting the drawbacks of other types of pylon.

“…The shape of the pylons are assumed to be an aesthetic feature as the effects of pylon shapes are not so prominent for structural design of short span cable-stayed bridges. However, it is imperative to use certain pylon shapes in case of long span cable-stayed bridges in order to satisfy structural safety [27][28][29][30]. Accordingly, this study examined the effect of two different pylon shapes of a long span cable-stayed bridge that is postulated to span the Izmit Bay in Kocaeli, Turkey.…”

In recent decades, the demand for complex and economical engineering structures with great aesthetics has been on the rise and the cable stayed bridges also take their share of this interest. Besides many advantages cable-stayed bridges are quite flexible, hence susceptible mainly to dynamic actions such as impact loads, wind effects and seismic excitations. In this context, this study focused on the effect of A and H shape reinforced concrete pylons on the seismic behavior of a long span steel triple box-girder cable-stayed bridge that was presumed to be located in an earthquake-prone region in Turkey. The 3D models of the bridge were constructed using SAP2000 software and the time history analysis have been carried out considering cable sag, large displacement effects. The seismic responses of the bridges are compared in terms of axial force on cables, deflections on the pylons and the deck.

“…It was concluded that the inverted Y-shaped pylon is naturally more appropriate for both curved and straight cable-stayed bridges. Shah et al [30] performed linear and nonlinear analyses for bridges supported by three different configurations such as H-shape, A-shape & inverted Y-shape under aerostatic loading. They concluded that the H-shape gives higher straining action than the inverted Y-shape and the A-shape.…”

Seismic performance of cable-stayed bridges with different geometric conditions

Cable-stayed bridges have gained greater coverage in the last few decades. This study focuses mainly on two parameters. Firstly, the shape of pylons; the performance of many shapes is investigated after being exposed to an earthquake. Secondly, the effect of changing deck width of an inverted Y-shaped pylon with variation in main span length. The numerical study was performed using MIDAS civil software. It was concluded that the most efficient pylon shape in terms of seismic performance was that of pyramid shape followed by a delta shape. In addition, it was found that changing deck width for the same main span gives a negligible difference to normalized shear force.
