Certainly! Here's the transcription of the image text: --- **(5) Check if the section is properly designed to resist the max. bending Mu?** ### Structural Design Example #### Diagram The diagram depicts a structural layout with two beams labeled "A" and "B". The span dimensions are: - **Beam A**: 24 feet - **Beam B**: 30 feet (both spans are 24 feet in another direction) #### Specifications - **Concrete Strength**: \( f'_c = 3 \, \text{ksi} \) - **Steel Grade**: Grade 60 Steel - **Concrete Type**: Normal Weight Concrete (NWC) - **Cover**: 1.5 inches - **Stirrups**: #4 stirrups #### Loads - **Dead Load (DL)**: 70 psf (not including self-weight) - **Live Load (LL)**: 40 psf (No Live Load Reduction) #### Beam AB - Dimensions: \( b = 12'' \), \( h = 24'' \) - **Reinforcement**: - \( 4 \# 8 \) bars for the main reinforcement - #4 stirrups positioned vertically at 24 inches This illustration and accompanying notes provide important parameters for analyzing and designing beam AB following typical structural engineering practices.

Question 1.

please answer and show your solution

True or false? The strength of under reinforced conc. section is controlled by yield stress of steel (reinforcements).

From the given trusses below, determine the force in the member DE. (kN) Hint: V = -20.9 kN Note: Use two (2) decimal places in the final answer. G H R P M 1.5 m L к 75 kN 75 kN 9 equal bays at 3.0 m each 3.0 m

Assume that the clamp shown has been tightened on wooden planks being glued together until P = 420 N. Determine the stress in A and D Find the location of the neutral axis

Statics - Zero Force Members1. Identify the zero-force members in the truss shown. 2. Redraw the truss without the zero-force members included.

A snow load transfers the forces shown to the upper joints of the Pratt and Howe roof lattices shown below. Ignoring the horizontal responses on the supports ( \(A x=Ex=0 \)) a) Determine the forces in all members using the joint method. Pratt Roof Truss System: AA A 2 Rods Pull Push CC=5,7 WIDTH (m) x=2 y=3,4 height (m) z=4,2 X 1 BB H 2 y 3 CC G y BB 5 D F X Pratt Roof Truss System SOLUTION: 6 AA E A 4-digit number must be written after the comma. For example 14.7845. Forces (kN) AA=4,2 BB=4,2 A

Hand written and clean writing please

Find 5 internal forces of the truss members, Also Find all zero force member. Thank you.
