Teaching-learning in civil engineering research courses is a challenge and even more in the current context of the Covid 19 pandemic, taking into account that laboratories and field works are not available. Nevertheless, it is also an opportunity to optimize the use of didactic and technological resources that enable the students to use approaches to study different kinds of engineering problems as well as contributing to their development as researchers. This study allowed to collect, through a validated questionnaire, the perception of 148 students who were in the last year in the Civil Engineering career at the Universidad Privada del Norte, and the results revealed that 61% of them were "in agreement" with the usefulness of numerical modelling techniques as a teaching resource for research.
In Peru, construction of dwellings using confined masonry walls (CM) has a high percentage of acceptance within many sectors of the population. It is estimated that only in Lima, 80% of the constructions use CM and at least 70% of these are informal constructions. This mean that they are built without proper technical advice and generally have a high seismic vulnerability. One way to reduce this vulnerability is by reinforcing the walls. However, despite the existence of some reinforcement methods in the market, not all of them can be applied massively because there are other parameters to take into account, as economical, criteria for seismic improvement, reinforcement ratio, etc. Therefore, in this paper the feasibility of using five reinforcement techniques has been studied and compared. These reinforcements are: welded mesh (WM), glass fiber reinforced polymer (GFRP), carbon fiber reinforced polymer (CFRP), steel bar wire mesh (CSM), steel reinforced grout (SRG). The Multi-Criteria Decision Making (MCDM) method can be useful to evaluate the most optimal strengthening technique for a fast, effective and massive use plan in Peru. The results of using MCDM with 10 criteria indicate that the Carbon Fiber Reinforced Polymer (CFRP) and Steel Reinforced Grout (SRG) methods are the most suitable for a massive reinforcement application in Lima.
