Current studies lack probabilistic evaluations on the performance of fault-crossing bridges. This paper conducts seismic fragility analyses to evaluate cable-stayed bridges with effects fault ruptures. Synthetic across-fault ground motions are generated using existing simulation methods for low-frequency pulses and high-frequency residuals. Incremental dynamic analysis is utilized generate resp...

This paper presents the results and interpretations of static dynamic tests that were executed on a newly built cable-stayed steel-concrete composite bridge during final proof testing. A brief description structure, testing methodology, used instrumentation are presented. Then, test widely discussed interpreted in order to evaluate performance also understand usefulness each performed framework...

Nagisa Bridge, a single span footbridge, was recently completed in Aomori prefecture, Japan. The structure of this bridge is a hybrid structure of cable-stayed prestressed concrete bridge and steel suspension bridge. It is the first application as this structure type of bridge in the world. Concrete girders near pylons are supported by stay cables. Steel girders are supported by suspension cabl...

Traditionally, a trial-and-error procedure is carried out to design cross-sectional areas of stay cables in cable-stayed bridges. This design process is monotonous, expensive, time-consuming, and incapable of finding the optimum design solution. The aim of this study is to develop a robust design optimization technique in order to achieve the minimum cross-sectional areas of stay cables. The de...

Abstract Many researchers have carried out experimental and numerical investigations to examine building structures’ response explosive loads. Studies of bridges subjected blast loads are limited. Hence, in this study, we present a case study on cable-stayed bridge, namely, Charles River Cable-Stayed Bridge-Boston, assess its robustness resistance against the progressive collapse resulting from...

This paper studies for the first time effect of spatial variability ground motions (SVGM) with large intensities on inelastic seismic response pylons which are responsible overall structural integrity cable-stayed bridges. The svgm is defined by delay earthquake at different supports, loss coherency waves and incidence angle motion. An extensive study conducted bridges ‘H’- inverted ‘Y’-shaped ...

The seismic response characteristics of a cable-stayed bridge are closely related to the structural system. At same time, influence height gravity center cannot be ignored in system selection bridges. For convenience, make scheme comparison and preliminary design stage bridge, judgment criterion low was proposed, based on simplified calculation fundamental frequency bridges with two kinds combi...
