On January 15, 2018 at 11:49, the west pylon of the cable-stayed Chirajara Bridge collapsed during construction of the bridge girder. The collapse led to the total destruction of the pylon, together with the erected span of the bridge girder. Authorities reported nine fatalities resulting from the collapse.In this case study, the findings of the detailed investigation into the failure mechanism of the bridge are reported. In addition, selected drawings used for construction, geotechnical aspects, and deficiencies in the bridge design are presented, together with observations made during site visits and interviews with relevant parties.

Fourteen years on from its last edition, Cable Supported Bridges: Concept and Design, Third Edition, has been significantly updated with new material and brand new imagery throughout. Since the appearance of the second edition, the focus on the dynamic response of cable supported bridges has increased, and this development is recognised with two new chapters, covering bridge aerodynamics and other dynamic topics such as pedestrian-induced vibrations and bridge monitoring. This book concentrates on the synthesis of cable supported bridges, suspension as well as cable stayed, covering both design and construction aspects. The emphasis is on the conceptual design phase where the main features of the bridge will be determined. Based on comparative analyses with relatively simple mathematical expressions, the different structural forms are quantified and preliminary optimization demonstrated. This provides a first estimate on dimensions of the main load carrying elements to give in an initial input for mathematical computer models used in the detailed design phase. Key features: Describes evolution and trends within the design and construction of cable supported bridgesDescribes the response of structures to dynamic actions that have attracted growing attention in recent yearsHighlights features of the different structural components and their interaction in the entire structural systemPresents simple mathematical expressions to give a first estimate on dimensions of the load carrying elements to be used in an initial computer input This comprehensive coverage of the design and construction of cable supported bridges provides an invaluable, tried and tested resource for academics and engineers.
