Development of Dissipative Steel Column-Base Connections for Steel Moment-Resisting Frames under Seismic Loading

In capacity-designed steel moment resisting frames (MRFs), column base connections feature a strong-base/weak-column design philosophy. Prior studies on fixed-end wide flange steel columns featuring seismically compact cross sections subjected to coupled a ...

Uplift mechanics of unanchored liquid storage tanks subjected to lateral earthquake loading

Konstantinos Bakalis

Motivated by the seismic response of unanchored liquid storage tanks, their uplift mechanism under strong lateral loading is examined. Using three-dimensional finite element models, nonlinear static analysis is conducted to define the moment-rotation relat ...

Modelling reinforced concrete coupling beams designed for low-to-moderate seismic regions

Lisa Imperatori

Reinforced concrete (RC) coupling beams are often used to transfer and resist the earthquake loads. Coupling beams can improve significantly the stiffness and the strength of the all lateral resistant structure. By performing inelastically they decrease th ...

Consistency in Solving the Inverse Problem of the Voce-Chaboche Constitutive Model for Plastic Straining

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa

This paper focuses on an inverse problem involving a commonly used material model in structural steel applications—the Voce-Chaboche model. In particular, the paper proposes an approach focused on obtaining a consistent set of material parameters that accu ...

Seismic analysis of reinforced concrete walls typical for Colombian construction

During the life of a structure, this one will be subject to a large number of solicitations. The objective of the civil engineer is to understand the behaviour of structures when they are subject to actions to ensure that these actions will not lead to fai ...

Seismic design of non-dissipative embedded column base connections

Dimitrios Lignos, Hiroyuki Inamasu

Embedded Column Base (ECB) connections in seismically resistant steel moment frames are commonly designed to be stronger than the connected column, to protect them from inelastic actions. This relies on estimation of demands induced by the column and the s ...

Behavior of iron-based Shape Memory Alloys under Cyclic Loading Histories

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Diego Isidoro Heredia Rosa, Masoud Motavalli, Alexander Riley Hartloper

Shape memory alloys (SMAs) have gained considerable attention in a broad range of engineering applications. In particular, iron-based SMAs (Fe-SMAs) have been recently developed and used as a cost-effect method for prestressed-strengthening of civil struct ...

Experimental investigation on the deformation capacity of lap splices under cyclic loading

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Danilo Tarquini

Correct detailing and positioning of lap splices is essential in order to prevent premature failure of reinforced concrete structural members. Especially before the introduction of capacity design guidelines, lap splices were often placed in member regions ...
