Increasing the coking process flexibility permits to face coke and steel market requirement. But changing process parameters such as coking temperature, time and blend composition can have consequences on the masonryies lifetime. Coke oven masonries are large structures composed of thousands of bricks and mortar joints. To avoid a high computational cost, a model combining homogenisation and submodelling is proposed. Bricks and mortar are replaced by a Homogeneous Equivalent Material (HEM) for which the behaviour depends on the joint state. The HEM properties are determined thanks to brick-mortar interface behaviour , experimentally characterised at high temperature. To refine the evaluation of local stress, which causes the joint failure, a submodelling technique is used.
