Estudo de concretos com adição de nanosílica submetidos à ação combinada de cloretos e CO2
(Universidade Federal de São Carlos, 2019-05-29)
Corrosion of reinforcement is one of the most severe pathological manifestations that can affect reinforced concrete structures, and the main aggressive agents of corrosion are chloride and CO2. Chlorine ions can cause ...
Desenvolvimento de algoritmo e programa de análise de estruturas em concreto armado levando em consideração as etapas construtivas e a variação das características do concreto com o tempo
(Universidade Federal de São Carlos, 2019-04-30)
The structural analysis of reinforced concrete buildings fabricated on site is usually done considering the structure in its final state, with the load applied on a given date and the concrete with its characteristic values. ...
Fabricação e caracterização de espuma de gesso para aplicações térmicas e acústicas
(Universidade Federal de São Carlos, 2017-12-12)
Due to existence in abundance in Brazil, low energy consumption, less fuel quantity in its production process, not being flammable and recycling possibility, gypsum is extremely viable in civil construction. Among its ...
Programa gráfico livre para a análise de lajes de edificações de concreto armado usando o modelo de grelha equivalente
(Universidade Federal de São Carlos, 2015-05-05)
It’s presented in this work a graphic program that allows the analysis (calculation of
