Concrete construction requires a formwork that shapes the structural sections and resists the concrete's weight, representing between 40% and 60% of the overall concrete costs, so the construction team must make cost-effective decisions throughout the project. This research compares the technical and economic performance, unit cost, and the number of metal and wood formwork applications in constructing shear walls in 80 single-family units assembled in 4 real estate units. To reach the yield value of 3,501.18m2, with the metal formwork, 31 uses were required at the cost of 5,873.13 USD; on the other hand, with the wood formwork, 51 uses were necessary at the cost of 14,289.79 USD. After 20 uses, comparing the wood formwork with the metal formwork, the latter was 66% more efficient.
Peru is located in a seismically active location due to the interaction of the Nazca and South American plates, as well as surface faults that cause significant earthquakes across the continent. These seismic episodes generate seismic forces that affect structures, frequently resulting in substantial material and human losses in Peruvian sensitive buildings. Peru's most recent significant seismic events were in 2001 in Arequipa and 2007 in Pisco, with magnitudes of Mw 8.4 and 7.9, respectively. When these earthquakes happened, Peru lacked the instrumentation necessary to record them, and hence only a few sites documented them. As a result, the goal of building an accelerograph network at the National University of San Antonio Abad del Cusco's headquarters was proposed. The development of an accelerometer network would allow for an improvement in the administration of seismic data. This included determining the technical elements of an accelerograph network, its installation, infrastructure, measurements, unit costs, budget, and plans. As a result of the investigation, a suggestion is made to implement KINEMETRICS, REFLEK 130 SMA and 130 SMHR accelerographs with a resolution of 24 bits on a server model PROLIANT DL380 G9. Additionally, it would include internal equipment such as battery installation, battery cable connection, and fastening sensor cable terminals; as well as exterior equipment such as GPS, ethernet, power, and Wi-Fi module installation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
