Frame Beamcolumn imperfection - Virtual Lab

The following application allows to obtain the behavior of in-plane and out-of-plane frames by calculating the resistant capacity of compressed and Bended frames with a I-section, sensitive to lateral buckling. To do this, the magnitudes of the equivalent imperfections inside and outside the plane are obtained and the imperfect structure is analyzed.

The objective is to determine the internal forces in perfect and imperfect frames with linear and non-linear behavior and to determine the resistance of the sections used in both beams and columns.

The geometry of the frame, beam and column section, dimensions, materials, loads, and in-plane and out-of-plane boundary conditions are selected. Different pots are obtained as results that show the stresses and movements of the perfect and imperfect structure in linear and non-linear calculation, and the proximity of the sections to their ultimate resistance. The values used by default give an example that can be understood with knowledge of mechanics of materials and steel structures. The results give different plots with displacements and internal forces that can be easily understood.

The two-level mutual trust-based quality assurance scheme has been adopted:

• at the university level: Universitat Politècnica de València has applied its internal quality assurance procedures and structures to the proposal of Frame Beamcolumn imperfection - Virtual Lab it submitted to ENHANCE and to its implementation - the related learning activities,
• at the Alliance level: the body composed of Education Officers has made decisions regarding the inclusion of Frame Beamcolumn imperfection - Virtual Lab proposed by Universitat Politècnica de València to the Innovative Learning Campus part of the joint ENHANCE educational offer, based on the compliance with the formal requirements and ENHANCE goals.
