Experimental proof of the effectiveness of timber panels in the seismic retrofit of URM buildings
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Recently there has been a growing interest by both academia and the industry in the possibility of using timber as a strengthening material for the seismic retrofit of unreinforced masonry (URM) buildings. This possibility ...
Timber-based seismic retrofit of a 5-storey RC structure built in 1955
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The paper presents a study on the seismic behaviour of a 1955 masonry-infilled reinforced concrete (RC) building subjected to two alternative timber-based interventions to reduce its seismic vulnerability. The first ...
Retrofit and Repair of Reinforced Concrete Columns with Active Confinement
(New Zealand Society for Earthquake Engineering, 2023-04-19)
There are too many reinforced concrete (RC) columns built before the 1970s without sufficient transverse reinforcement. Past earthquakes have demonstrated the vulnerability of such columns and the need for their retrofit. ...
Earthquake strengthening clay brick masonry parapets – proof-tested solutions
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Unrestrained unreinforced clay brick masonry (URM) parapets are found atop of a large number of vintage URM buildings. Parapets are typically cantilevered wall structural elements that form decorative and ornamental features ...
Seismic strengthening of RC walls using FRP to prevent axial failure
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Reinforced concrete (RC) walls with insufficient compressive strain capacity at the boundary region are vulnerable to premature axial failure, limiting the drift capacity. A solution to strengthen these deficient RC walls ...
