What types of constraints did Covid-19 cause in duration of activities on different construction projects?
Post-tensioned AASHTO Type III girders are to be used to
support a deck with unsupported span equal to 90 feet. One level
of Grade 270, 10 x 0.6" Ø 7-wire strand are used to tension the
girders. The girder is simply supported at both ends. The anchors
are located 2" from the neutral axis at the supports while the
eccentricity is measured at 14" at the midspan.
Use maximum values for ranges (table values).
The tendons are encased in flexible metal sheathing. Assume and
loadings are placed immediately after stressing.
Determine the stresses at the top and bottom of the beam,
including the stress at the level of steel after three years.
Given the following parameters:
F'c = 5000 psi
Fy = 240 ksi (Bonded, Stress-relieved)
Fu = 270 ksi
=
Es 29,000 ksi
Ec = 4,030 psi
Fj = 235 ksi
A = 1x0.6" 07-W.S. = 0.217 in²
Yc = 140 lbs/ft³
ΔΑ = 3/8"
RH = 33%
Superimposed Service Load = 10 kips/ft (excluding self-weight)

Assuming that Poisson's ratios of sand and soft clay are 0.3 and 0.5, respectively. Use numerical integration approach. For the calculations, use layers (below the bottom of the footing) of thicknesses: 1 m; 1.5 m, and 2.5 m. (b) Determine the primary consolidation settlement beneath the center of the footing. (c) Redo Part (b) if OCR=1.1. Note: Use the 2:1 method to determine the stress increase below the footing. For parts (b) and (c), use the one-dimensional consolidation theory.arrow_forwardConsider the cross-sections illustrated in the next slides. Implement a cross-sectional analysis based on a layered discretisation of the cross- section as required at the following. 1) Develop the implementation of an analysis to estimate the nonlinear response of the composite steel-concrete section, of the reinforced concrete section and of the steel section shown in following slides (using material nonlinear models provided in the support files). Provide the details of the numerical implementation with clear explanations of all steps. Hint: the implementation can be done in Excel. 2) Discuss how the 3 cross-sections (shown in the next slides) compare to each other in terms of embodied carbon under the condition that the cross-sections possess the same nominal moment capacity (i.e. the peak moment achieved in the moment-curvature diagram).
