For all problems you must draw strain-stress-force diagrams AND check $$A_s?A_{s,min}$$ as well as any assumptions you make in the calculation process. Even if the $${\mathrm{A}}_{\mathrm{s}}?{\mathrm{A}}_{\mathrm{s},\min }$$ check fails, complete the requested calculations as stated below. Consider the simply supported beam shown below. The design specifies a 28-day peak concrete compressive strength is $$4500\mathrm{psi}$$ and Grade 60 steel. The bottom layer of reinforcement contains five \#10 bars and the top layer contains four $$\#8$$ bars. For the given beam, determine: a) Reduced nominal moment capacity, $${?}_f{M}_n$$. b) Whether $${?}_f{M}_n$$ is adequate to meet the maximum factored moment, $$M_u$$. c) Curvature associated with nominal moment capacity, $${?}_n$$.
