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=11″and h=26″. Span length is 18ft

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

Calculate the weight in k/ft, of a reinforced concrete beam that has a cross section b=13″and h=24″. Span length is 16ft

Since our reading of the case, CEMEX has developed IT and Business Process Evolution (BPE) organization, together with an Evolution Committee. Back-office processes were grouped together, leaving a total of four core processes out of eight. One BPE leader, with full-time responsibility, was appointed to focus on the effectiveness and improvement of each one of the four processes. The team developed and maintained an IT platform for submitting and refining ideas. The team involves country representatives and ensures more openness to accept cultural issues.   Which best describes this stage in the evolution of enterprise architecture?

Determine the amount of steel area required for a one-way slab with a span of 16ft, f’c=4,000 psi, fy=60,000 psi and Mu=9.7 k-ft. Choose bar size and spacing check for maximum required spacing.

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?

for Problems 17, 18 and 19, Pick 2 of these three.  (Write Skip for the one you do not want graded).   A building owner is evaluating the following alternatives for leasing space in an office building for the next Three years:                                     Net lease with CPI adjustments.  The rent will be $20 per square the first year.  After the first year, the rent will be increased by half of the amount of any increase in the CPI.  The CPI is expected to increase 4 percent per year.                         Net lease with steps.  Rent will be $18 per square foot the first year and will increase by $2.50 per square foot each year until the end of the lease.  All operating expenses will be paid by the tenant.               Gross lease.  Rent will be $32 per square foot each year with the lessor responsible for payment of all operating expenses. Expenses are estimated to be $8 during the first year and increase by $1 per year thereafter.               Gross lease with expense stop and CPI adjustment (Gross Lease PLUS).  Rent will be $22 the first year and increase by half of the amount of any change in the CPI after the first year with an expense stop at $8 per square foot.  The CPI and operating expenses are assumed to change by the same amount as outlined above.               a.         Calculate the effective rent to the owner (after expenses) for each lease alternative using a 12 percent discount rate. 1. Net lease with CPI adjustments                                2. Net lease with steps                        3. Gross lease                      4. Gross lease PLUS                   b.         How would you rank the alternatives in terms of risk to the Owner? (Briefly justify your ranking.)                        C.  Which would the Tenant prefer?  (explain why)
