Seismic Assessment/Retrofit
Compusoft Engineering has considerable research and project experience in the seismic assessment of new and existing structures using advanced analysis techniques. We specialise in the design of seismic retrofit, including the use of state of the art stabilising and strengthening techniques. Our considerable experience in the non-linear analysis and behaviour of structures allows us to develop optimal strengthening solutions, thus minimising disruption on site and costs to our clients.
Earthquake engineering services include;
- SEISMIC SCHEMING AND ANALYSIS
Compusoft Engineering regularly provides guidance on the development of seismic schemes for buildings and structures and provides seismic analysis services on a consulting basis. Typically for the design of new structures linear procedures such as equivalent static and modal response spectrum analyses are undertaken to develop the set of seismic demands that comply with all relevant strength and deformation provisions based on proposed structural configuration. The results of the analysis are provided to the client in a suitable form to enable element design to be completed.
- SEISMIC EVALUATION AND RETROFIT
The seismic evaluation of structures considering seismic performance with respect to strength and serviceability requirements are undertaken using advanced analysis techniques such as Non-Linear Pushover and Time History procedures. Assessments are undertaken in accordance with current internationally accepted procedures such as those published by The New Zealand Society for Earthquake Engineers, ASCE, FEMA and ATC. Where the seismic evaluation shows the structure to be deficient, retrofit measures can be designed, either to alter the response of the building, or to strengthen elements that are subject to excessive loadings or deformations. Compusoft also has specialist experience in the use of retrofit solutions incorporating base isolation and damping. Strengthening works are tailored to satisfy the specific needs of each building and client.
