Breakback Corners
Bridge Slab Behavior at Expansion Joints

7.2.1 Breakback Corners
“Breakback” is the term used by TxDOT to describe an alternate, simplified method of constructing the acute-angle corners of a skewed slab(Figure 7.3).
In this detail, the slab end is perpendicular to the girders for a transverse distance of 2 ft (607 mm), beyond which it is skewed.
All transverse reinforcement in the overhang is parallel to the slab end.
"Breakback"은 기울어진 슬래브의 예각 모서리를 구성하는 대체적이고 단순화된 방법을 설명하기 위해 TxDOT에서 사용하는 용어입니다(그림 7.3).
이 상세도에서 슬래브 끝단은 2ft(607mm)의 횡거리까지 거더에 수직이며, 그 이상은 기울어집니다.
바닥판 캔틸레버의 모든 횡보강은 슬래브 끝단과 평행합니다.

Temperature effects_maturity
In the CEB-FIP Model Code 90 , maturity is a concept used to predict the rate at which concrete gains strength based on temperature and time. Eq. (2.1-87) is used to calculate the maturity-adjusted time $$ t_T$ $ , which accounts for the effects of temperature on concrete's strength development. \( S=\int d^{4} x\left(\frac{R}{2 \kappa}\right) \) begin{eqation} S=\int d^{4} x\left(\frac{R}{2 \kappa}\right) end{equation} Definition of Equation (2.1-87): The maturity-adjusted time $$tTt_T tT$$ is calculated as: $$tT=∫t0texp[QR(1T0−1T(τ))]dτt_T = \int_{t_0}^{t} \exp \left[ \frac{Q}{R} \left( \frac{1}{T_0} - \frac{1}{T(\tau)} \right) \right] d\tau tT=∫t0texp[RQ(T01−T(τ)1)]dτ$$ Where: tTt_T tT = maturity-adjusted time (in days) tt t = real elapsed time (in days) t0t_0 t0 = start time for the calculation (usually 0) QQ Q = activation energy for hydration process, typically around 33,500 J/mo...
