Calculate the weight in k/ft, of a reinforced concrete beam that has a cross section b=15″and h=28″. Span length is 25ft

Determine the amount of steel area required for a simple supported beam with b=10″, h=18″, f’c=4,000 psi, fy=60,000 psi and Mu=145 k-ft. Choose a size and amount of bars and check for beam width.

Determine the amount of steel area required for a simple supported beam with b=15″, h=27″, f’c=4,000 psi, fy=60,000 psi and Mu=390 k-ft. Choose a size and amount of bars and check for beam width. 

Calculate the weight in k/ft, of a reinforced concrete beam that has a cross section b=14″and h=26″. Span length is 19ft.

Calculate the actual factored Moment, Mu of a slab that has a 250 psf dead load that includes the slab weight and a service live load of 250 psf. Slab span is 25ft. Final result should be in k-ft

Calculate the actual factored Moment, Mu of a slab that has a 225 psf dead load that includes the slab weight and a service live load of275 psf. Slab span is 15ft. Final result should be in k-ft

for Problems 17, 18 and 19, Pick 2 of these three.  (Write Skip for the one you do not want graded).   CAM charges for retail leases in a shopping mall must be calculated.  The retail mall consists of a total area of 3.2 million square feet, of which 850,000 square feet has been leased to anchor tenants that have agreed to pay $2.50 per rentable square foot in CAM charges.  In-line tenants occupy 1.65 million square feet, and the remainder is common area, which the landlord believes will require $8.75 per square foot to maintain and operate each year.  If the owner is to cover total CAM charges, how much will in-line tenants have to pay per square foot?

In a random sample of 40 cases there were 25 successes and 15 failures. We want to construct a 95% confidence interval to estimate the proportion of successes in the population. StatKey was used to construct a bootstrap sampling distribution using count = 25 and sample size = 40. The bootstrap distribution was approximately normal with a standard error of 0.076 Construct a 95% confidence interval to estimate the proportion of successes in the population using the standard error method. Use the following formula, where SE is the standard error:        statistic +/- (2 * SE)

Calculate the weight in k/ft, of a reinforced concrete beam that has a cross section b=12″and h=25″. Span length is 20ft

for Problems 17, 18 and 19, Pick 2 of these three.  (Write Skip for the one you do not want graded).   A retail lease for 12,000 square feet of rentable space is being negotiated for a THREE-year term.                         Option A calls for a base rent of $25 per square foot for the coming year with step-ups of $1 per year each year thereafter.  CAM charges are expected to be $3 for the coming year and are forecasted to increase by 5 percent at the end of each year thereafter.                         Option B calls for a lower base rent of $23 per square foot with the same step-ups and CAM charges, but the tenant must pay overage rents based on a percentage lease clause.  The clause specifies that the tenant must pay 25 percent on gross sales over a breakpoint level of $920,000 per year.  The owner believes that the tenant’s gross sales will be $850,000 during the first year but should increase at a rate of 10 percent per year each year thereafter.             a.         If the property owner believes that a 15 percent rate of return should be earned annually on this real estate investment, which option is best for the property owner?             b.         What if sales are expected to increase by 8 percent per year Which would the TENNENT Chose?
