Modelling the Behaviour of Light-Frame Wood Stud Walls Subjected to Blast Loading

摘要

This paper presents analysis using a non-linear material predictive model considering partial composite action for wood light-frame stud walls subjected to blast loading. The proposed model was verified against data from an experimental program, where walls were tested statically and dynamically. The validity of the current provisions of the Canadian blast standard is evaluated and discussed. The modeling results show a tendency for increased capacity and stiffness under high strain rates. The results also demonstrate that neglecting partial composite action yields predictive capacity values that are too conservative.
