The present research aimed to contribute to seismic vulnerability in buildings of limited ductility walls. For this, fragility curves have been developed in walls of limited ductility of 10 cm of thickness according to the PACT of the P-58 FEMIA. Data were collected from 20 experimental tests carried out in the structure laboratory of the Peruvian Center for Seismic Investigation and Disaster Mitigation of the National University of Engineering. Fragility curves express the probability that a limited ductility wall will reach or exceed a selected damage state for a given drift or displacement level. From the fragility curves it ¡is possible to observe that the probability of exceeding 50% of damaging state 2 (maximum wall strength) is: 13mm for MDL-CCA1, 16mm for MDL-CCA2, 20mm for MDL- 2mm for MDL-CCA9, 4mm for MDL-CCA5, 4mm for MDL-CCA6, 5mm for MDL-CCA7, 4mm for MDL-CCA8, and 4mm for...

This project was carried out under the financing of the "VI Competition of financing for research projects Private University of Tacna (UPT)". In this project, tests have been carried out on the piles and the death of masonry, which were built using the masonry unit to block II of the Martorell brickyard. With the results of the essays and the compilation of other essays carried out by our university students, the values ​​of f'm and v'm have been determined. The base of all the studies has been elaborated a proposal of formula of the minimum density of the walls, which allows us to calculate the minimum length of the walls that is needed in a masonry building built with load-bearing walls of the blocker II so that it can resist a severe earthquake.

It studies the beams of great can’t, which are used to withstand large loads or for architectural conditions. This investigation consists in the determination of the design of a discontinuous beam in totality, both in load and in geometry, using the strut-pull technique, therefore, using bibliographic information of similar research works, the structural design of this beam, the technique is recommended by the Peruvian Standard E.060. Subsequently, modeling was carried out in the AbaqusCAE software to determine steel reinforcement efforts, percentage of damage parameters, Von Mises and Tresca efforts, percentage of cracks and crushing percentage, resulting in a good design for this type of structures, which was verified in the software where it has a good behavior, concluding that, for samples with considerable discontinuities it is recommended to use the Strut and Tie technique.

The little regulation existing in our country regarding construction highlights the fact of the existence of a great deficiency in the design as in the execution of the same. One of the affected components and the one dealt with in this article are the reinforced concrete stairway systems, systems that are not very valued but are of vital importance in a building, which present a design flaw due to various factors, for which purpose a software that analyzes and designs various systems of reinforced concrete stairs in order to implement it in various projects. Achieving the realization of it and concluding a favorable impact on Civil Engineering.

The city of Tacna is in seismic silence, waiting for a large earthquake and the environmental effects that this causes. The objective of the investigation was to determine the prevailing frequencies and periods of some earthquakes registered in the city of Tacna, using the Fourier analysis and spectrum. Earthquakes of the present century, of a magnitude greater than 5.0 Mw and from different near, intermediate and distant seismogenic sources were selected. The research used the Fourier mathematical model to process seismic signals, from the time domain to the frequency domain, then, the prevailing frequencies and periods of the different signals were analyzed and learned. For better signal processing, a code was created in Matlab to perform the calculations, which were then verified using the Seismosignal software. The predominant frequencies of earthquakes from close sources vary from 2...

The study of the characterization of solid waste was carried out in the district La Yarada -Los Palos, Tacna Province, in order to analyze the home and non-domicile waste of homes, markets, schools, shops, hardware stores and curators. The methodology described by the Ministry of the Environment (2018) was used to determine the quantity and characteristics of solid waste by random sampling. The per capita generation of household solid waste was 0.470 kg/hab-day, in the physical composition, organic matter was found in greater quantity was 56.77 %, the average uncompacted density was 224,682 kg/m3 and the compacted 305,664 kg/m3. In terms of non-home waste, it was determined that educational institutions generate more solid waste at 38.47%, followed by grocery stores with 28.53%, fruit shops with 8.60%, restaurants 7.21% and places with 4.10%. With the information obtained, the manual lan...
