FireSolver is a web app for the fire design of steel members to EN 1993-1-2, with thermal actions from EN 1991-1-2. The app computes the critical temperature for tension, compression, bending and combined compression and bending. Flexural buckling and lateral-torsional buckling are included, with the elastic critical moment Mcr. From the critical temperature, the app computes the steel heating under the fire curve, the fire resistance time and the class achieved, from R 30 to R 240. The fire curve is the standard ISO 834 curve, the hydrocarbon curve, the external fire curve or a user-defined curve. For protected members, the app gives the protection thickness required for the specified class, for fire boards (gypsum, calcium silicate, vermiculite) or spray coatings. The section factor Am/V is computed from the section and the number of sides exposed to fire. The section catalogue has HEA, HEB, HEM, IPE, IPN, CHS, SHS and RHS profiles, in steel grades S235 to S460. Checks are saved per member and grouped by project. The app generates PDF reports per member and per project. The app runs in the browser. Data is stored on servers in the European Union (Frankfurt). The interface is available in English and Romanian.
