Influence of the cross section shape on the behaviour of SRG-confined prismatic concrete specimens (2015)
Journal Article

The effectiveness of the steel-reinforced grout (SRG) jacketing technique in increasing both strength and deformation capacity has been substantiated by experimental evidence [1-3]. What it has not been addressed yet is the influence of the cross sec... Read More about Influence of the cross section shape on the behaviour of SRG-confined prismatic concrete specimens.

Flexural behaviour of reinforced concrete jacketed columns under reversed cyclic loading (2014)
Journal Article

The objective of the present study is the development of an analytical model for predicting the response under reversed cyclic loading of structural members with ‘old-type’ detailing, strengthened with reinforced concrete (RC) jacketing.
