Numerical modelling of the cyclic behavior of timber-framed structures

Abstract

The present paper presents a study on the applicability of numerical models in predicting the global response of timber-framed shear walls during earthquake events. Based on previous in-plane cyclic testing of traditional timber frames with and without masonry infill, numerical models were developed to describe the cyclic response of traditional timber frame walls including flexural behavior, pinching and strength degradation. The numerical models were developed in the finite element software OpenSees with calibrated springs representing nailed connectors found in traditional half lap joints. Based on the calibrated models a study was conducted on the timber frame wall with brick infill model by varying wall configuration and analysing cumulative energy dissipation and the effect of slenderness and load capacity with increasing drift. A good correspondence was obtained with the experimental data and future work will include the application of the model to whole buildings.

Influence of Joints on the Seismic Response of Traditional Timber Frames in Turkey

“…As there are very different types of connections, it is expected different dissipative behaviors. This fact justifies the extense experimental research work that has been carried out in the last years with different timber frame systems (Lukic et al, 2018).…”

“…Secondly, in terms of casualties’ result, TF building conduces the highest value of casualties. Timber frame structures are earthquake-resistant because of the dissipative capacity of the joints and their ability to dissipate large amounts of energy (Lukic et al 2018). Yet, TF structure experienced the flexural mechanism of ground shaking and it decreases the structure of the building (Lukic et al 2018).…”

In the case of Bantul area, TF buildings are typically Joglo (Javanese wooden) house which the construction technique of roof type is futuristic and complex.…”

Numerical Modelling of the Seismic Performance of Romanian Traditional Timber-Framed Buildings

“…A simplified strategy was used by modelling the panel through an equivalent frame with the non-linear behaviours lumped at the connections, and the model was implemented in OpenSees [11] as proposed in [8], [12]. Figure 6b shows the frame schematization consisting in linear elastic timber elements with translational and rotational springs at their connections.…”
