Re applied to simplify the compression and tensile pressure distribution, as shown in Figure 14d. , are defined as the compression and tensile pressure distribution, as shown in Figure could be the are defined because the equivalent coefficients of compression Piceatannol Protocol strain distribution, and 14d. , equivalent coeffiequivalent coefficients of compression tension distribution, and would be the is 0.74, and is 0.25 cient of tension pressure distribution. In distinct, is taken as 0.92, equivalent coefficient of tension strain distribution. In specific, compression f’y is 0.74, and is 0.25 [27,42]. [27,42]. The yielding tension of steel bars beneath is taken as 0.92, may very well be reasonably adopted The yielding anxiety ofunderbars below compression f’ y may very well be reasonably adopted as the because the yielding anxiety steel tension fy. yielding anxiety below tension f y .Figure 14.

Substituting Equation (8) in to the above equilibrium equations, the only unknown value could obtained. Therefore, the following equations can be applied to estimate the ultimate moment in the UHPC beams prestressed with external CFRP tendons. For xcu t:Mu = 0.five f t bw (h2 – x2 ) + f pu Ap hp + f y As h0 -0.5 f c (b – bw )t2 – 0.5 f c bw x2 – f y Ay as 2 (13)For xcu t:Mu = 0.five f t bw (h2 – x2 x2 ) + 0.five f t (b – bw )(t2 – 2 ) + f pu Ap hp + f y As h0 -0.five f c bx2 – f y As as (14)exactly where h0 is the helpful depth from the cross section; and a’ s would be the powerful depth of your compression reinforcements. The comparison involving the experimental and the prediction final results from the specimens are listed in Table four. The maximum error was no more than six , plus the average error was no a lot more than 3 . It indicated that the proposed system could appropriately predict the ultimate moment of UHPC beams prestressed with external CFRP tendons.Table four.
