Shaking Table Tests on RC Frames strengthened with Simplified Friction Damper
(New Zealand Society for Earthquake Engineering, 2023-04-19)
This study investigates the behavior of two reinforced concrete (RC) frames strengthened with simplified friction damper subjected to dynamic loading conditions. The simplified friction damper was designed with intent to ...
Trends in systematic site residuals with geomorphic categories for New Zealand ground-motion instrument sites
(New Zealand Society for Earthquake Engineering, 2023-04-19)
This study investigates systematic site-effects from prediction residuals of physics-based ground-motion simulations for a database of small magnitude (i.e., 3.5 ≤ MW ≤ 5) shallow crustal earthquakes in New Zealand. The ...
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 ...
Feasibility of capacity spectrum method for analysis of low damage structural systems with friction connections
(New Zealand Society for Earthquake Engineering, 2023-04-19)
The use of friction connections for low damage design of new structures has been increasing over the past few years. These connectors have a high energy dissipation ratio and are relatively economical to fabricate and ...
Earthquake Design Pressures from Soil Interaction on Building Basement Walls
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Free-standing retaining walls are usually designed for earthquake loads using the Mononobe-Okabe method and assuming cohesionless soil backfill. The method assumes active pressure develops as a consequence of a failure ...
Post-disaster building functionality: preliminary findings of a systematic review
(New Zealand Society for Earthquake Engineering, 2023-04-19)
During a natural hazard event, buildings are likely to experience some sort of damage, thus limiting their ability to function as intended. The severity of the ensuing consequences for various stakeholders and the community ...
Seismic Restraint of Non-Structural Elements – Evolving Design Thinking
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Seismic Restraint of non-structural elements has received increased attention in the past decade within the New Zealand building industry. Clients and Project Managers are now often coupling Seismic Restraint design with ...
Deformability of lap splices in RC structural walls
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Severe structural damage associated with lap splices located near the foundation of reinforced concrete (RC) structural walls has been recorded in the field after recent major earthquakes in Chile, New Zealand, and Taiwan. ...
Dynamic analysis of tall reinforced concrete walls designed with minimum vertical reinforcement
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Analysis of tall walls subjected to the earthquake ground motions highlights the amplified dynamic moment response at the mid-height due to the higher mode effect. The amplified moment demand may result in unexpected ...
Seismic Performance Comparison of New Zealand and Japanese Concrete Moment Frames
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Observations of the performance of reinforced concrete (RC) buildings after the 2016 Kumamoto earthquake in Japan showed buildings designed using Japanese standards resulted in less damage and downtime compared to buildings ...
