... Working with cylindrical test bodies, 10 cm diameter x 20 cm height, heated to 300°C, cooled both slowly and rapidly, Galleto & Me- neguini [3] obtained reductions, respectively, of 4% and 21% only on the ... See full document

... Based on the experimental development and on the results obtained, we may conclude that the addition of the residue from improvement dimension stones in tactile-loor hydraulic tile increased the lexural strength of the ... See full document

... Table 3 shows results of lexural strengths for each kind of curing procedure adopted for HSC concrete specimens. As one can see, results point out a loss of 8 to 22% on the lexural strength for all dry HSC ... See full document

... = 3 , 6 MN and in order to simplify the discussion of the problem the following simpliications are adopted: P it is the effective force of prestressing in the considered age and constant throughout the ... See full document

... The material model number 1 refers to the Solid65 element. The Sol- id65 element requires linear isotropic and multilinear isotropic mate- rial properties to properly model concrete. The multilinear isotropic material ... See full document

... ber of bars. The basic values for this analysis were: 30 cm, 4 m, 40 mm, 0,7 and 4 bars, respectively, h = 1,5 b and ℓ 0,l = ℓ/2. This analysis also served for comparison of results by means of eq. 3 (Eurocode 2) ... See full document

... In addition, the development of new polymeric materials, such as CFRP-Carbon Fiber Reinforced Polymer, GFRP- Glass Fiber Reinforced Polymer and AFRP-Aramid Fi- ber Reinforced Polymer has allowed a great flexibility for ... See full document

... The ultimate (collapse) load is the maximum force achieved in the diametral compression test, which leads to the ultimate limit state for the pipe. The service load is one for which a crack with open- ing of 0,25 mm will ... See full document

... This is due, maybe, to the structural calculation, because this build- ing is relatively slender. Out of the 14 existent columns in the build- ing, 5 of them would demand intervention type I4 for which shoring would be ... See full document

... Speciically, regarding the numerical study of the shear stress on the reinforced concrete structures, there is a number of theoretical and experimental studies on concrete beam subjected to shear [1- 3] although ... See full document

... The study of the effects of LCVs on the most common structural systems in highways of the state of Sao Paulo began at the De- partment of Structural Engineering of the Sao Carlos School of Engineering through El Debs et ... See full document

... Hobbs and Stein [7] studied the behaviour of two pile caps through theoretical and experimental analysis. Seventy models were as- sayed in a reduced scale at the ratio 1:3. Researchers developed an analytical ... See full document

... The low curves are necessary to appropriately describe the ce- ment based materials such as non-Newtonian luids, as their vis- cosity depends on the shear rate and the shear duration [15]. When a concrete is submitted to ... See full document

... Bulk density of recycled and natural aggregates was determined by the method proposed in NM 45/00 – Aggregates – Determina- tion of bulk density and empty voids. For each type of aggregate, bulk density was determined ... See full document
