In RFEM 6, it is possible to define line welds on lines between surfaces and calculate the weld stresses using the Stress-Strain Analysis add-on. 本文将向您展示操作方法。
钢材的防火性能较差。 The thermal expansion for increasing temperature is very high compared to that of other building materials, and might result in effects that were not present in the design at normal temperature due to restraint in the component. As temperature increases, steel ductility increases, whereas its strength decreases. Since steel loses 50% of its strength at temperature of 600 °C, it is important to protect components against fire effects. In the case of protected steel components, the fire resistance duration can be increased due to the improved heating behavior.
