Research of long-term behaviour of non-prestressed precast concrete beams made continuous
(Elsevier BV, 2014)
Despite the extensive analytical and numerical research carried out in the last two decades on the long-term behaviour of continuous concrete beams composed of precast units, only limited number of experimental data is ...
Time-dependent analysis of composite and prestressed beams using the slope deflection method
(Springer Verlag, 2015)
The paper presents the viscoelastic analysis of composite and prestressed beams using the slope deflection method. For the fixed-end frame element, considering the viscoelastic behavior of concrete and relaxation of ...
Creep of recycled aggregate concrete: Experimental database and creep prediction model according to the fib Model Code 2010
(Elsevier Ltd, 2019)
Recycled aggregate concrete (RAC) is a promising solution to addressing the sustainability issues raised by concrete production. However, its long-term properties are not fully characterised, especially creep behaviour, ...
Matrix Stiffness Method for Composite and Prestressed Beam Analysis Using Linear Integral Operators
(Springer Verlag, 2015)
In the paper, the analysis of composite and prestressed beams using the matrix stiffness method is presented. The stiffness matrix for the frame element with a moment release at one end and the vector of equivalent nodal ...
Design for time dependant effects in precast concrete bridge girders made continuous with cast-in-place deck and diaphragm
(Czech Concrete Society, 2011)
There are many benefits when precast bridge girders are made continuous for live load, such as: lower costs, improved durability, improved structural integrity, improved ride quality, etc. Material nonlinearity of concrete ...
Long-term behavior of composite concrete girders made continuous
(Precast Prestressed Concrete Institute, 2010)
Time-dependent effects play an important role in the design process of concrete structures. In order to predict time-dependant effects in concrete structures, engineers need reliable data for creep and shrinkage properties ...
Long-term behaviour of reinforced beams made with natural or recycled aggregate concrete and high-volume fly ash concrete
(Elsevier Ltd, 2018)
Six simply supported reinforced concrete beams were tested under sustained loads for 450 days. The beams were made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC) and high volume fly ash concrete ...
