Fig. 1 Load distribution of Shield Tunnel Segment 2.2 Material Model and Main Parameters Shield tunnel lining is usually precast in factory and assembled in the shield tail.
In designing segments, ignoring the weakening effect of the joints leads to the overestimation of design axial force, and thus causes unnecessary cost due to extra reinforcement and material.

Due to the flame temperature it is more than clear that the most commonly used materials in the immediate vicinity of the flame or in contact with it begins to burn very easily.
Knowledge of candle part materials design is important in regard to the release of chemical particles which can react with historically valuable frescos and other worthy decorative elements of the building interiors.
This theoretical experiment will be followed up by an experiment investigating the burning of candles and the impact of the released particles to surrounding materials in a real experimental chamber.
