En este enfoque, el tamaño de la losa se diseña de tal manera que no más de un set de ruedas del vehículo quede sobre ella, con el objetivo de reducir las tensiones. La investigación asociada a esta innovación ha estado focalizada en pavimentos urbanos e interurbanos donde se han generado ahorros económicos de hasta un 25%. Por otra parte, los pisos industriales de hormigón tienen solicitaciones distintas a los caminos y carreteras, las cargas de tráfico son diferentes y los efectos climáticos considerados no son los mismos debido a que el piso industrial se encuentra, por lo general, cubierto por una estructura. El objetivo de este artículo es analizar el estado tensional de losas cortas bajo solicitaciones de pisos industriales mediante modelación de elementos finitos para generar recomendaciones de diseño. Esto se lleva a cabo mediante un análisis factorial que considera variables como localización del pavimento, fecha de construcción, geometría de las losas y tráfico. Los resultados indican que las losas cortas si pueden generar ahorros significativos en ciertos pisos industriales, pero que no son la mejor opción en todos los escenarios analizados. Sin embargo, son una muy atractiva alternativa para pisos industriales tipo bodega de uso masivo.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: Short slabs are a concrete pavement innovation that represents a change of paradigm in the traditional design (where the number of joints is limited). In this innovative approach, the concrete slab is designed in a way that no more than one set of vehicle wheels is actually on the slab. In this way, the stresses are reduced. The research related with this innovation has been focused in urban and interurban pavements, where the costs have been reduced even until 25%. On the other hand, the traffic demands over industrial floors are different from concrete pavements of streets or highways. In addition, the weather demands are different because a roof covers industrial floors. The objective of the present article is to analyze the stresses of short slabs for industrial floors using finite elements models in order to generate design recommendations. For that, a factorial design including variables as the pavement location, time of construction, slab geometry and traffic is defined. The results show that short slabs can generate significant costs reductions in certain industrial floors, but that they are not necessarily the best option for all the analyzed scenarios. However, short slabs are an attractive alternative for industrial floors commonly used as warehouses.]]></p></abstract>
