Twelve uncracked or pre-cracked strengthened reinforced concrete beams and six beams without strengthening, all of them in 6 different sizes, were tested.
Adjusting for maternal BMI pre-pregnancy strengthened this association (β = −11.36, p = 0.01) and further adjusting for chorioamnionitis, birth weight and race/ethnicity did not alter this association.
Existing design code methods were found to provide conservative design strength of the FRP strengthened pre-stressed RC deck units.
5.3, effects of CFRP pre-stressing of strengthened reinforced concrete beams on two parameters of ULCC and energy depreciation ability studied.
In a similar study, Li et al. (2002) strengthened pre-cracked RC beams with carbon fibre reinforced polymer (CFRP) and GFRP sheets and investigated the combined effect of boiling water and UV-light.
Rather, Global Fund financing complemented and further strengthened pre-existing efforts to address TB at the national government level (E. Santos-Filho, personal communication, May 23 , 2012.
The Education Workstream Report from Midwifery 2020 [ 26] specifically noted 'that knowledge and skills regarding public health and well-being need to be appropriately strengthened within pre registration programmes' (p13).
Considering Fig. 10, the following notes are obtained: Open image in new window Fig. 10 Load displacement curves of beam number 2 with tensile steel rebar percentage of 1.25% for both states of not pre-stressed CFRP and pre-stressed CFRP The ULCC of the beam strengthened with not pre-stressed CFRP was 92.19 kN at the ultimate displacement of 20.86 mm.
Two un-strengthened control beams were considered, four beams that were pre-cracked before the application of the AFRP sheets and one beam that was strengthened without pre-cracking were tested.
Two un-strengthened control beams, four beams that were pre-cracked before the application of the AFRP sheets and one beam that was strengthened without pre-cracking were tested.
But the failure seems to have strengthened the Pres.
