Time-Dependent Strains in Axially Loaded Reinforced Concrete Columns
TLDR
In this article, an exact method for estimating the time-dependent strain in reinforced concrete (RC) members is presented, which can be used to estimate the time dependence of reinforced concrete members.Abstract:
Time-dependent strains in reinforced concrete (RC) members are usually estimated using approximate algebraic methods. This paper presents an exact method for estimating the time-dependent s...read more

Time-dependent behaviour of circular steel tube confined reinforced concrete (STCRC) stub columns subjected to low axial load
Yun-Long Guo,Yue Geng,Lian-Yu Qu +2 more
TL;DR: In this article, a numerical model was proposed for calculating the long-term deformation of STCRC stub columns based on the cross-sectional analysis method and the step-by-step method, and was benchmarked against the available test results.

Time-dependent behaviour of circular steel tube confined reinforced concrete (STCRC) slender columns
TL;DR: In this article , a reliable analysis method was proposed and validated by the available test results, which showed that the steel tube can contribute up to 12.6 % of axial stiffness of the composite columns, which is different from that predicted based on plane section assumption.

Creep and shrinkage prediction model for analysis and design of concrete structures - model B3
TL;DR: In this paper, a model for the characterization of concrete creep and shrinkage in the design of concrete structures is recommended, which is simpler, agrees better with the experimental data and is justified better theoretically than the previous models.

Pervasiveness of Excessive Segmental Bridge Deflections: Wake-Up Call for Creep
TL;DR: In this paper, the authors investigated the long-time deflection evolution of Koror-Babeldaob (KB) bridge in the island nation of Palau and showed that the terminal logarithmic deflection trend can be predicted well by a simple extrapolation of the measured 1000-day deflection under the hypothesis of proportionality to the compliance function increment since the time of span closing.

The B4 Model for Multi-decade Creep and Shrinkage Prediction
TL;DR: In this article, a new model, labeled B4, is presented, which can overcome some of the shortcomings of the CEB-fib, ACI, JSCE and GL prediction models for concrete creep and shrinkage.
