1 CEE 120 Spring 2016 – Final Exam Review Details:-7 - 10 pmon Tuesday, May 10, 2016 in 234 Hearst Gym-Covers material from all lectures and HW 1 to HW 11. -Bring ID, writing utensils, straightedge, calculator, yourself -No blue book needed. Gameplan:-Review lecture notes/reader/previous HWs. -Read through this midterm review: it’ll contain all you need to review. Go to office hours for any clarifications. -Do past final exams. PRACTICE PRACTICE PRACTICE. -Go to Moehle’s office hours. -If you plan on starting to study on Monday night, just go straight to doing the practice exams. Topics Covered: 1)Analysis of beams/frames, trusses, cables.- For each type of structure, know how to: i)Find reactions and internal forces.ii)Draw axial (N), shear (V), moment (M) diagrams, and deflected shapes.iii)Find degree of static indeterminacy and check stability.2)Load paths and gravity calculations3)Wind and seismic loading4)Principle of virtual displacements (PVD) and influence lines5)Principle of virtual forces (PVF) and deflections.6)Wood, steel, and reinforced concrete (RC) designBasic Procedure for Solving Structures: (frames, trusses, cables, and combined structures)1)Check degree of static indeterminacy/stability. If determinate and stable, solve.2)Draw free body diagram (FBD)3)Find any solvable reactions via global equilibrium (of entire structure)4)Make cuts (i.e. at hinges, through loops, reactions, etc.) and draw FBDs.5)Apply static equilibrium to find internal forces and reactions.6)Draw final global FBD (with all labels and loads), N, V, M diagrams, deflected shape.*Note: For combined structures (structures that contain frame, trusses, and/or cable elements), you canmake a cut at the joints to split the different types apart and solve them individually. Don’t forget the action-reaction forces.
2 Overview: (to help you guys see the big picture) This class in a nutshell: Design: Demand ≤ CapacityASD: (wood design) 𝑓𝑓𝑖𝑖≤ 𝐹𝐹𝑖𝑖′(stresses) LRFD: (steel and RC design) 𝑈𝑈 ≤ 𝜙𝜙𝑆𝑆𝑛𝑛e. g. bending: 𝑀𝑀𝑢𝑢≤ 𝜙𝜙𝑀𝑀𝑛𝑛, shear: 𝑉𝑉𝑢𝑢≤ 𝜙𝜙𝑉𝑉𝑛𝑛, deflections-U (demand) based on factoredloads -LRFD load combinations (gravity only): 1)1.4D 2) 1.2D + 1.6L Find demand: -Using the tributary area methodand the concept ofload paths, we can:- transform gravity, wind, andseismic loadinginto demand forces acting on a structure (various loads and procedures given in ASCE 7- 10) - find what loads(psf, plf, kips) are acting on each member(e.g. beams, columns, girders, etc.) -With our demand loads, we can analyze our member via statics! Find degree of static indeterminacy and check stability. Find reactions and internal forces. Draw axial (N), shear (V), moment (M) diagrams, and deflected shapes. -We can also use the principle of virtual displacementsto find unknown real forces. - Use PVD to create influence lines to find the maximum possible forcethat can occur under combined dead and live loads.
