The seismic vulnerability and inadequate behaviour of existing school buildings observed
during past earthquakes in Italy have raised awareness of the need to upgrade their …

Existing reinforced concrete (RC) buildings designed for gravity loads only (GLD) are
widespread worldwide even in seismic prone areas, including Italy, showing a significant …

Exterior beam-column joint is typically the weakest link in a limited-ductile RC frame
structure. The use of diagonal haunch element has been considered as a desirable seismic …

Seismic assessment of a building will typically require consideration of its nonlinear force–
displacement response. Such information can be estimated from pushover analysis, also …

The improvement of the seismic performance of existing buildings is majorly accomplished
by adopting one or more retrofitting interventions. The selection of the latter is generally …

The new guidelines for the seismic assessment of existing buildings recently introduced by
the New Zealand Society for Earthquake Engineering (NZSEE) recommend the Simple …

There is a renewed interest around the world to do fundamental research on novel materials
to enhance the overall response of structures under seismic loading. Engineered …

This paper addresses the stress field of reinforced concrete (RC) beam–column joints
retrofitted with haunches. Design of such solution currently assumes internal forces …

The Stick model is a MDOF system composed of masses lumped at the story level,
connected in series by nonlinear shear link elements suitably calibrated to simulate the …

Generally, beam-column joints are taken into account as rigid in assessment of seismic
performance of reinforced concrete (RC) structures. Experimental and numerical studies …
