In this paper, a novel numerical method for strucural analysis, called the Hybrid Discrete-Finite Element Method (HybriDFEM), is presented. In this method, a structure is modeled as an assembly of rigid blocks in contact. All the deformation is conce

This work explains the development of a viscous damping model using the condensed tangent stiffness of the structure. It eliminates the spurious damping forces and avoids the high levels of damping presented by the condensed damping model defined wit

The substitution of reinforcing steel with shape memory alloys has been offered as a solution for reducing residual displacements in reinforced concrete (RC) walls. This paper presents some recent experimental and numerical research efforts conducted

Although distributed plasticity beam elements include formulations that verify a strict equilibrium of the axial forces along the element length, known as force-based (FB) approaches, the classical conventional displacement-based (DB) elements show a

When using a plastic hinge analysis, the displacement capacity of a reinforced concrete wall is highly dependent on the assumed value for the plastic hinge length (Lp). Most of the expressions that are available in the literature have been derived sp

Reinforced concrete core walls form the backbone of millions of buildings internationally, bracing the structure against wind and earthquake loading. Due largely to plan asymmetry, a torsional response of a building is possible, where the core wall w

This paper presents a tangent-stiffness-proportional viscous damping model independent of the geometric stiffness for time-history response simulation of frame structures. The nonlinear geometric effects are considered using a corotational formulatio

This work compares the force-based (FB) design of moment resisting frames, as proposed in the next generation of Eurocode 8, with a complete displacement-based (DB)design approach, also introduced in the future code. After describing some of the evol

The seismic performance of buildings depends critically on the stiffness and strength of storey diaphragms. Whilst for modern reinforced concrete or steel structures the connection between floors and lateral resisting members is often assumed as mono

Reinforced concrete buildings typically utilise structural (or shear) walls as their primary lateral load resisting system. The U-shaped wall is a popular cross-sectional shape used in construction as it can enclose a service core, elevators (lifts),
