Seismographs measure the movement produced by an earthquake through a record called seismogram, the seismogram is a graphical representation of seismic waves. Magnitude, one of two ways of measuring an earthquake, is a way of quantifying the energy released by an earthquake; the magnitude is calculated from seismic records (seismograms) and thus quantifies the energy released in the focus of an earthquake. Nowadays, it is known that the slow accumulation of energy along specific zones in the Earth's crust over time produces ruptures in the area under stress. The Gutenberg-Richter ratio (law G-R, 1954) represents the correlation between the magnitude of the earthquakes and its repetitiveness over a period of time, and it allows quantifying this relationship. The value b is the slope (in logarithmic scale) of the distribution of the G-R ratio; its estimate is directly related to the average stress in a seismic/seismogenic source. In this investigation, the b value will be determined. The value b - a constant approximately equal to 1.0 - is calculated as an initial part in the formulation of the source line threat model; its temporal variation (the variation of the b-value) allows describing the distribution of probabilities, the range of possible and probable magnitudes, and the rate of occurrence of the earthquakes of a specific seismic source. In the present work the regression analysis (and Maximum Likelihood Estimation, MLE) will be used to quantify the relationship between the number of earthquakes N and magnitude ML within the region called Borde Llanero: Huila -Meta-Cundinamarca-Boyacá-Casanare, and dominated by the East Frontal Fault System (EFFS). The quantification of the frequency-magnitude relationship will be made from data recorded since 1993, and until 2017, by the National Seismological Network of Colombia RSNC (for its acronym in Spanish).Ítem Determinación de la resistencia a tensión por carga axial en conexiones ortogonales de guadua inyectadas con polipropileno, reforzadas con barras número 3 y número 4.Poveda Sierra, Camilo Andrés; Sandoval Cubillos, Alejandro; López Palomino, Paulo MarceloInitially, the research shows the state of the art regarding to the construction with guadua and more specifically different types of connections and their combination with other materials.

The preparation of mortar mixtures added with TiO2 in the rutile phase was carried out, in percentages of 0%, 2%, 3%, 4%, 5% and 6% with relation to the weight of cement. The components of the mortar were characterized, in addition, properties such as fluidity, compression resistance, change in length and expansion, absorption rate, unit mass, porosity, variation in volume and weight, determination of pH and study by means of a microscope were evaluated. electronic sweep. The addition of titanium dioxide increased the fluidity of the mixtures by up to 16%. Additions in percentages less than 5% met the design compressive strength, however, it was not superior to the mixture without addition. Under conditions of chemical aggression, the mixture with the addition of 2% recorded the smallest decrease in resistance. For the addition of By 2%, the secondary absorption rate and porosity were decreased and there was less variation in volume and weight. All test specimens were highly affected after 13 weeks of sulfate exposure. The SEM exploration allowed us to observe the formation of ettringite, gypsum and thaumasite products without evidencing a significant contribution of titanium dioxide to the sulfate attack.Ítem Guía para interventoría técnica en contratos de obra de estabilización mediante anclajes activos en tierra.Ruiz Galeano, Edward Estid; López Palomino, Paulo MarceloIn the field of civil engineering, professionals are often in the task of supervising and supervising technical supervision of works for the protection, containment and hydraulic management of slopes, and in many cases there is no methodological tool for this. . Which or which are the criteria to control, supervise and monitor in the execution of said works are the main questions that the controller faces in the execution stage of the projects. Although we know that not all the works have the same characteristics, if we recognize similarities that serve as a theoretical basis to establish a comparison and control tool in the works, in the same way with the technical standards that we often use to guarantee the correct development and operation of civil products, thus this monograph seeks to carry out a methodology guide in the implementation of technical supervision in the execution of civil works for the stabilization of slopes and hydraulic management.Ítem Guía para la inspección de redes contra incendio a base de agua en edificaciones residenciales en usoAvila Montejo, Cindy Paola; López Buitrago, Yerson Leonardo; López Palomino, Paulo MarceloThe operations of review, inspection and maintenance of the RCI fire networks must comply with the requirements of the Colombian regulations (NSR -10) and with the NFPA international standards in force; therefore, this work aims to generate tools that allow to create follow-up controls for the time of realization of the technical inspection and / or assessment of the RCI of conventional systems of residential buildings, so that the inspector, controller and / or hydraulic supervisor gives an objective assessment of their condition.
