8.6 Code Practice Question 1

Selected Problem Answers

For the beams shown below determine the reaction forces and describe the shear and moment diagrams using the force method. For each construction, use the specified redundant forces to do the force method analysis. All elements accept the same $EI$ unless otherwise indicated.
For the frames shown beneath determine the reaction forces and describe the shear and moment diagrams using the force method. For each construction, employ the specified redundant forces to do the force method analysis. All elements have the same $EI$ unless otherwise indicated.
For the trusses shown below determine the reaction forces and the internal axial forces in all members using the forcefulness method. For each construction, use the specified redundant forces to practise the forcefulness method assay. All elements have a constant $EA$ unless otherwise indicated.
For the beams shown beneath determine the reaction forces and depict the shear and moment diagrams using the strength method. For each structure, employ the specified redundant forces to exercise the strength method assay. All elements have the same $EI$ unless otherwise indicated.
For the frames shown beneath determine the reaction forces and draw the shear and moment diagrams using the strength method. For each structure, utilize the specified redundant forces to practise the force method analysis. All elements have the same $EI$ unless otherwise indicated.
Solve Problem ane(d) for the loading shown with the addition of a support settlement of $35\mathrm{\,mm}$ at support B. Presume $E = 200\mathrm{\,GPa}$ and $I=250\times ten^half dozen\mathrm{\,mm^4}$.
Solve Problem ane(b) for the loading shown with the addition of back up settlements of $thirty\mathrm{\,mm}$ at support A, $ten\mathrm{\,mm}$ at support B, and $45\mathrm{\,mm}$ at support C. Presume $E = 200\mathrm{\,GPa}$ and $I=\mathrm{\,400\times ten^6}{mm^four}$.
Solve Problem 4(b) for the loading shown with the improver of back up settlements of $15\mathrm{\,mm}$ at support B, and $10\mathrm{\,mm}$ at support C. Assume $East = seventy\mathrm{\,GPa}$ and $I=500\times 10^6\mathrm{\,mm^4}$.
Solve Problem 3(b) without any external loads, where members AB, AC and CE have undergone a temperature increase of $fifty\mathrm{\,^\circ C}$. Assume that $\alpha = 12\times 10^{-6}\mathrm{\,/ ^\circ C}$.
Solve Problem iii(c) without any external loads, where member CE has undergone a temperature subtract of $-30\mathrm{\, ^\circ C}$ and member AE was fabricated $7\mathrm{\,mm}$ likewise long. Assume that $\alpha = 12\times 10^{-6}\mathrm{\,/ ^\circ C}$.
