- The contractor would like to increase the shore spacing to allow more clearance for access below the formwork. What are three changes in the design of the formwork (not changes in the concrete or the construction live loading) that could be made to accommodate the increase in spacing. No calculations needed. Just list the formwork design changes.Under reinforced section...defineMinimum reinforcement in column?

Generally produce a factor on the dos and don’ts considered when arranging the detail of reinforcement.
- The total length of exterior walls of a residential building is 650 lf. The 8-foot long 2x4 studs are spaced 16 in. OC or less. The drawing of the building shows there are 20 corners requiring three studs. Studs are installed on single 2x4 bottom sill plates and capped by double 2x4 top plates for the entire length of the walls. Both bottom and top plates are 16-ftlong each. Prepare a list of materials for the wall studs, corner studs, sill plates, and top plates. For each of the materials, show the nominal dimension, number of pieces of each length, the length ofa lumber, and the total linear feet. Estimate the total direct cost and cost per linear foot of wall for furnishing and installing the studs and plates. Assume $0.75/bf for lumber, $30.00/hour carpenters, and $24.00/hr for laborers. Use the average value in Table 12.10 for the labor-hoursDesign and detail a one-way slab both end continuous having span of 6m. The slab is to carrya uniform LL = 6.12 kPa, superimposed DL = 2.53 kPa. Assume fc’ = 23 MPa and fy = 345 MPa for the main and temperature bars. Use 12mm for the main reinforcement and 10mm fortemperature bars.What is the equivalent rebar spacing (in mm) for a 120mm thick one way slab with 1m unit design strip if the required area of reinforcement is 600sqmm? fy=276MPa, fc=21MPa, db=10mm, Cc=20mm.
