Determine the size modification factor, ψs, for a rectangular beam with b = 16 in. and d = 23 in., three galvanized No. 6 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 40 stirrups located every 12 in. along the span. Assume 8,000-psi normal-weight concrete and a clear cover of 2 in.

A common example of a column supporting axial forces and bending about two perpendicular axes is a corner column in a frame.

Determine the transverse reinforcement index, Ktr, for a rectangular beam with b = 16 in. and d = 22 in., four epoxy-coated No. 9 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 4 Grade 60 stirrups located every 12 in. along the span. Assume 7,000-psi lightweight concrete and a clear cover of 1.75 in.

Match the board performances with the definition of movements that take place in that technique.

Muscles should be stretched to the feeling of pain as slight muscle tension is not effective.

In the acronym “Park SMART” ­– the letter M stands for:

Compute the axial compressive strength Pn and moment capacity Mn of the following tied column when the largest strain in the concrete is 0.003 and the strain in the tension reinforcement is 0.003. Note that you should not include φ in the answer and that you should not consider Pn,max.b = 12 in.h = 20 in.Clear cover to ties = 1.5 in.Number of longitudinal bars = 6Size of longitudinal bars = No. 6Size of ties = No. 4Concrete strength = 9,000 psiYield strength of longitudinal bars = 60,000 psiYield strength of ties = 60,000 psi

A rectangular beam has a cross section of b = 14 in., h = 26 in., and d = 23.5 in. It is reinforced with two No. 5 Grade 60 bars. The concrete strength is 5,500 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the transformed cross-sectional area of the bars, Ast.

Development length is the longest length of bar in which the bar stress can increase from zero to the yield stress.

Tied columns cannot be L-shaped.
