Heritage stone buildings are typically vulnerable to seismic events. Results of an experimental program were analyzed to evaluate the shear strength and intrinsic damping of stone masonry representative of the West Block of the Canadian Parliamentary

Concrete structures can dissipate seismic energy during moderate to severe earthquakes by deforming inelastically. The inelastic deformation should concentrate at specific locations, referred to as plastic hinges. An experimental program was conducte

SUMMARY Ductility and plastic rotational capacity of flexural elements constructed with concrete strengths up to 175 MPa were investigated experimentally. Ten exterior beam–column sub-assemblages were tested under cyclic displacements that represen

Unreinforced stone masonry is common in heritage structures worldwide. Unfortunately, these structures are susceptible to failure or severe damage when subject to dynamic or seismic loading. Conservation of historic structures is a challenge as the h

In seeking to understand the dynamic behaviour of historic stone structures, eight representative walls were constructed and tested under in-plane free vibration conditions. Each wall consisted of two wythes, one sandstone, one limestone, joined by a

Structures require ductility to withstand severe earthquake-induced loads and remain standing. A new method for modelling seismic displacement ductility is proposed here, in which a fuzzy inference system is utilized to include the uncertainty in the

In rigid frames, performance during major earthquakes requires plastic hinges to form at beam-ends, and for them to have sufficient energy and damping capacity to accommodate the earthquake energy. An experimental program was carried out to investiga

A successful seismic design for a reinforced concrete element is one that can postpone the shear failure until the required ductility and deformation capacity are obtained. After flexural yielding, shear deformations are the main causes for strength

High-strength concrete (HSC) has several benefits in high-rise concrete buildings; however, its structural use in active seismic regions may be questioned due to the lower ductility of such concretes. In addition, seismic macro-models being used curr

Few studies have examined the behavior of flexural elements constructed with high strength concrete (HSC) and ultra-high strength concrete (UHSC) under cyclic loads. This experimental study investigates the seismic behavior of flexural elements const
