For a 10 story RC frame office building ( 100 ft by 100 ft footprint) located in downtwon Philadelphia :
a- Determine the lateral wind pressure (external) along the height of the building. Building Cateogry II, wind expeosure category B. Basic wind speed V= 90 m/h.
b- Determine the lateral seismic loadalong the height of the building using the equivalent lateral load procedure. Sc = 0.3g. Silt soil type.
c- Determine whether wind or earthquake load will govern the design.
Data : Floor height = 12 ft.Floor/roof slab thickness = 7 in.Superimposed dead loads ( flooring and false ceiling = 15 psf)
An automobile traveling at 30 miles per hour on level pavement with a coefficient of kinetic friction of 0.6. Weighs 3,000 lb. Sixty percent of its weight is on the front axle and 40% on the rear axle.
A dense sand has an effective friction angle of 43 and c'=0. A dry, 2.8-inch diameter sample is tested in drained triaxial shear with a confining pressure of 2500 psf. What axial load, P (in pounds), will be required to fail the sample?
A meter long steel plate with a rectangular cross section(10mm x 50mm) is resting on a frictionless surface under the sun.the plate temperature is measures to be at 40C.the plate is then moved into a cold room and is left to rest on a frictionless su..
A rectangular beam, simply supported over a span of 4m, is carryinga uniform distributed load of 5kN/m and a concentrated load of 5kNat the center of the beam.
A frictionless, incompressible steady flow field is given by V=2xyi-y^2j in arbitrary units. Let the density be ρ_0=constant and neglect gravity. Find an expression for the pressure gradient in the xdirection.
Deisgn a thrust block needed to resist the force generated by a 45 degree flanged regular elbow which carries a flow of 14 cfs. The diameter of the fitting narrows from 24 inches to 18 inches and the inlet pressure is 100 psi.
An aggregate blend is composed of 53% coarse aggregate by weight (sp. gr. 2.702), 43% fine aggregate (sp. gr. 2.621), and 4% filler (sp. gr. 2.779)/
Draw the FBD and the shear and bending moment diagrams. Label all minimums, maximums and zero crossing points as well as the slopes as constant, linear or parabolic.
You are a Project Manager on site where work for 3K.m. long Tunnel has been undertaken. The site is remote and takes about 2 days travel to nearest town. Supervisors, Technicians & Skilled Workers are engaged in dangerous / hazardous work.
Undrained shear box tests were carried out on a series of soil specimens with the following results:Total normal stress (kPa) Total shear stress at failure (kPa)
Two identical alloy specimens are being evaluated for use in a new fuel rod design. One sample was exposed to a fast neutron flux of 9 X 10^23 neutrons/(cm2*sec) at a temperature of 323°K for six weeks in a test reactor.
At a specified point on a highway, vehicles are known to arrive according to a Poisson process. Vehicles are counted in 20-second intervals, and vehicle counts are taken in 120 of these time intervals.
