CIVL 0016 Geotechnology - Middle East College

Learning Outcome 1: Analyse the stability of retaining structures; how to predict the performance of piled foundations; how to analyse the stability of slopes (including rock slopes); the application of the concept of seepage in permeable ground, the philosophy of Dam Engineering; and the basic concept of critical state soil mechanics

OBJECTIVES
i. To carry out the analysis and design of geotechnical structures specified in the assessment brief with considerable emphasis on sustainability and safety requirements
ii. To interpret the design outputs
iii. To prepare and submit a technical report that follows a standard report protocol

Question 1:
a) Supported by evidence in the literature, critically reflect on (i.e. in your own words) the circumstances under which pile foundations are necessitated - 200 words

b) After a thorough investigation of site conditions, it has been decided to provide design of a 3 x 4 pile group for a high-rise building in Muscat. Two sites were selected.
SITE A: a layered fine-grained soil consisting of loose clay underlain by stiff clay
SITE B: a layered coarse-grained soil consisting of loose sand underlain by gravely layer

Referring to your individual soil data, determine the ultimate structural load that can be allowed on the pile group and interpret your results.

Question 2:

a) It is required to check the stability of a layered soil slope shown below using any two methods of slices. In order to ensure accuracy of the method, a minimum of five (5) slices should be considered for analysis. Note however that the more number of slices the more the accuracy improves. Individual soil data is provided in a separate file in Moodle.

b) Appraise the critical state soil mechanics concept. You may evaluate this concept in relation to the classical soil mechanics currently followed in geotechnics. - 200 words

REPORT FORMAT

TABLE OF CONTENTS Provide a table of contents with corresponding page numbers.

INTRODUCTION
In the introduction part of your report, you are attempting to inform the reader about the rationale behind your work. In other words, you are justifying why your work is an essential component of the module you are taking - Geotechnology 2 (CIVL 0016). The introduction is written with the view of introducing the topic of your CW and setting it into a broad context, gradually narrowing down to your learning outcomes. You may also state what type of approach you will be using in your CW for the entire discussion of your topic. Suffice to write a maximum of one page introduction (half page is OK).

APPROACH
This section also covers the data collection and analysis methods, such as computer models (software), mathematical models, questionnaires, interviews, visual observations, document review, etc. Relevant soil parameters and calculations should be shown clearly.

DISCUSSION

The purpose of a results section is to present and illustrate your findings. Make this section a completely objective report of the results. The purpose of the discussion section is to provide an interpretation of your results and support for all of your conclusions, using evidence from your calculations and results, literature review and generally accepted knowledge, if appropriate. All evidences taken from the literature (i.e. research) needs to be supported by the CU-Harvard citation and referencing style. The significance of findings should be clearly described.

CONCLUSION
In academic writing, a well-crafted conclusion can provide the final word on the value of your analysis, research, or paper. Complete your conclusions with conviction I Consider the conclusion from the reader's perspective. At the end of a paper, a reader wants to know how to benefit from the work you accomplished in your paper. Include the following in your conclusion.
v How do the ideas in your report connect to what we have discussed in class, or to what scholars have written in their treatment of your topic?
v What new ideas have you added to the conversation? What ideas do you critique?
v What are the limitations of your data, methods, or results?
v What are the consequences of the strongest idea that comes out of your report?

CIVL 0015 Structural Mechanics

Learning Outcome 1) Demonstrate knowledge and understanding of the principles underlying advanced areas of structural analysis Present relevant information and calculations in a clear and unambiguous way

Learning Outcome 2) Interpret and evaluate experimental data in the context of the theory developed within this module.

Learning Outcome 3) Carry out non-routine calculations in order to apply structural theory to the solution of typical engineering design problems.

Assignment Objective
Principles of structural analysis introduced in module Structural Mechanics 3 will be extended to cover more advanced theories of analysis and design. The module will provide you with an introduction to, and in-depth study of, a range of analytical techniques and will equip you with the knowledge to undertake structural problems of a non-routine nature. In doing so, students develop their skills in using mathematical concepts to develop engineering theory

Assignment Tasks
(For more information refer the Marking Criteria of the Coursework as well as the report format)

i) An Entrance of an MPH (Multipurpose Hall) located in KOM (Knowledge Oasis Muscat) consists of a rectangular slab with an isotropic reinforcement with equal moment of resistance per meter run. Slab 1 is resting on 4 beams (Supports could be assumed as 2 sides fixed and 2 sides simply supported) and slab 2 is resting on 3 beams(All the 3 supports could be assumed as fixed). Slab 1 is accompanied by a partition wall of height 'H' m as shown in figure 1. The live load acting on the slab 1 is Q2 kN/m2 and slab 2 is Q2kN/m2. Weight density of the partition wall could be taken as 20 kN/m3 and that of concrete could be taken as 25 kN/m3. Slab thickness could be assumed.
a) Analyze the slab 1 and slab 2 by determining the ultimate yield resisting moment.
b) Design the slab 1 using Eurocode-2 from the obtained yield line moment with all the critical checks followed with structural and reinforcement detailing of the slab.
c) Locate the formation of yield line pattern and collapse load for slab 1
Note: - Details of slab dimensions, live load acting on the slabs, and wall height are provided in the excel sheet.

ii) Analyze the frame PQRS as shown in the figure 2a and figure 2b by determining the end moments using stiffness matrix methods. Column PQ is subjected to horizontal uniformly varying load. Supports P and S are fixed. Live load acting on the slab 3 is '03 kN/m2. Compare and interpret the manual calculation results with software results using STAAD Pro or Robot Structural analysis & design software. For the analysis of the frame consider the loads acting on the beam coming from the slab 3 and the partition wall. Also, consider the uniformly varying load acting on the column PQ for the analysis. Weight density of the partition wall could be taken as 20 kN/m3 and that of concrete could be taken as 25 kNirni.

Note:-Beam and column dimensions could be assumed and other relevant details are provided in the excel sheet for each student.
