To assess the knowledge and understanding of the analytical skills, critical thinking and software skills in the design and detailing of earthquake resistant multi storied building in Oman.
|
|
Learning Outcomes
|
On completion of this coursework the student shall be able to:
- Design of shear walls as vertical systems used to resist earthquake loads.
- Perform detailing requirements in seismic design.
- Develop skills of structural modeling using software.
|
Task(s)
Course work - Assignment (100% Weightage)
Shear walls are vertical elements of the horizontal force resisting system. In structural engineering, a shear wall is a structural system to counter the effects of lateral load acting on a structure. Seismic loads are the most common load that shear walls are designed to carry.
Figure1 shows the plan of multi-story construction (G+5) for a school building project in Oman. It is required to examine the earthquake resistant of the multi-story construction with shear wall in two principle directions.
(i) Write a brief abstract about the project (seismic design with shear wall) highlighting the concept, materials used and the method of construction which includes soil condition, building importance and seismic zone.[Weightage: 10%]
(ii) Prepare a structural plan, elevation and distribution of shear wall in the plan with grid lines in the horizontal (x-direction) and vertical (Y-direction) including naming of the grids in alphabetical order horizontally (in x-direction from left to right) and by numerical numbers vertically (in y-direction from bottom to top) respectively which includes column showing the proposed shear walls scheme in the two principal directions of the building.
[Weightage: 15%]
(iii) Analyse and design one shear wall manually as per EC8 which includes load calculation, base shear, distribution of horizontal seismic force, direct force, real torsional force, accidental torsional force, total force, maximum bending moment at base, maximum shear force at base, axial load calculation, load combination, design of flexural reinforcement in DCL condition.
[Weightage: 35%]
(iv) Carry our modeling and design of shear walls with gravity and earthquake forces using software STAAD Pro / ETABS as per Euro Code 8.[Weightage: 25%]
(v) Reinforcement detailing: Provide all relevant reinforcement details of shear wall both longitudinal section and cross section.[Weightage: 10%]
(vi) Student participation in class. [Weightage: 5%]
