In this paper, the seismic performance of offshore reinforced concrete (RC) bridges during their life cycle periods is assessed by the pushover analysis based on the concept of the force analogy method (FAM). The governing equations and implementation process of the proposed pushover method are first derived. The material nonlinearity is modeled by the local plastic mechanism, which is capable of simulating the monotonic strength hardening and softening behaviors of RC piers. The chloride ions corrosion effect for the RC bridges located in coastal areas is considered by using the deterioration model for the mechanical property of reinforcement steel. Besides, structural stability against overturning is considered by incorporating the geometric nonlinearity with the FAM. Since the initial stiffness matrices remain constant through the computation process, the advantages of the FAM, such as high efficiency and stability, are retained. A numerical example is carried out to illustrate the process of seismic performance assessment for offshore RC bridges with the FAM.

Major Factors

In recent years, there is rapid increase in the construction of high rise structures due to the increase in population, high cost of land and restriction in horizontal growth due to less space. The advancements in the development of technological solutions and construction methods of high rise structures led to the innovative structural systems. One of the important criteria that need to be considered in the design of high rise structures is minimization of lateral loads. Hence, the importance of lateral load resisting system increased than structural systems that resist gravitational loads. Lateral loading due to wind and earthquake are the major factors that have to be considered in the design of high-rise structures. Diagrid structural system is recognized as a unique system in construction of high rise structures which is a variation of tubular structures. It consists of inclined members instead of vertical columns in conventional structures to carry both gravity and lateral loads. It gains popularity due to its structural efficiency and aesthetic potential gained by its unique geometric configuration. The present work reviews studies regarding seismic performance assessment of steel diagrid structures, studies on seismic performance factors of steel diagrid structures, impact of shear-lag effect and comparative studies on diagrids. Diagrids are found to be an efficient structural system for high rise structures in terms of structural efficiency as well as aesthetics. Also, it provides more economy, in terms of consumption of steel, thus making it cost-effective and eco-friendly.
