Ítem Comparación de los métodos de cálculos estándar para la prevención y protección contra el fuego en el acero y la madera como miembros estructurales en edificaciones, según el código de la Society of Fire Protection Engineers (SFPE) aplicable a la Norma Sismo Resistente NSR-10 título J.Lugo Jara, Zully Estefania; Ojeda Castillo, Jesus Steven; Lopez Palomino, Paulo MarceloFire protection and prevention in buildings refers to all the necessary security measures for the construction, operation and maintenance of buildings. Thus, for example, structural members such as beams and columns are required to be fire resistant. Temperature increased in a building, produces that the constructive materials present transformations and/or changes in their mechanical properties. The heat fractures and breaks the work by expanding its components, modifying the different resistances of the structural materials, elastic moduli, critical loads and bearing capacity, which can trigger a collapse of the building. The fire stability of an element cannot have more time, under the effect of the braking temperature, its mechanical resistance is modified to a certain level (deformation). At that moment, we reach the critical temperature and a minimum reaction time (in minutes), so adequate protection of the wooden and steel structural elements of a building entails the prevention of possible collapse of the structure by the action of fire and protection of human lives. The 2010 Colombian Earthquake Resistant Regulation, Title J - Fire protection requirements in buildings, focus on the protection, resistance, detection and extinction against fires in buildings, but does not specify adequate protection in structural systems made of steel and wood, so a comparison has cavity on the standard calculation methods for fire prevention and protection in these two materials as structural members in buildings, between the code of the Society of Fire Protection Engineers (SFPE) and the Colombian Construction Regulations for Earthquake Resistant 2010 NSR-10, Title J.Ítem Herramienta informática para el cálculo de esfuerzos normales y cortantes V&M EstructuractZarate Ochoa, Andrés Camilo; Beltrán Leguizamón, Laura Tatiana; Lopez Palomino, Paulo MarceloAimed computer tool to get diagrams shear and normal stresses generated on beam's cross sections. Designed specially to be used by students from civil constructions technology and civil engeenering.Ítem Software de aplicación al cálculo de cargas, rotaciones,deflexiones y deformaciones de estructuras en 2D mediante análisis matricial de rigidez (Direct Stiffness Method) “Demat”Gonzalez Cobos, Cristian Felipe; Manrique Àlvarez, Juan Carlos; Lopez Palomino, Paulo MarceloThere are different ways of interpreting the structural behavior of a system through the Matrix analysis of rigidities. Constantly developing applications that facilitate their understanding. However, performing benchmarking results without supporting software becomes a costly task. Consequently, a traceability of the Construction of a complementary tool for the structure analysis course II is presented, which allows systematizing, visualizing and interpreting the matrix stiffness method of structures. The software facilitates the evaluation of the structural behavior of beams, trusses and portals in 2D through a visual Basic platform, according to the configurations, conditions and restrictions made by the user. Therefore, it supports the development of design criteria thanks to its versatility, showing and evaluating step by step the calculation of the element analyzed.
