Question

After the invention of computers, the slope deflection method is extensively used in the analysis of structures. Justify.

Answer #1

Slope deflection method is a displacement method, slope deflection method is extensively used in the analysis of structures after the invention of computers because of the following reasons.

1)This method takes into account only the bending deformations.

2)This method gives an understanding of stiffness matrix method which is the basis for most of the computer softwares currently used for structural analysis

3)The unknowns to be calculated can be easily put into a matrix form and this matrix can be easily solved for the unknown displacements and rotations by allowing a software program to run with less complexities,hence easing the calculation and process

For the following questions, circle "T" for True and
"F" for False:
1. The slope deflection method depends only on rotation at joints.
( ).
2. Generally there are two types of displacement. ( ).
3. In moment distribution method increased number of cycles would
result in less
accuracy. ( ).
4. Length of beam is one of the properties that used to calculate
relative stiffness. ( ).
5. Members connected to a joint share the unbalance moment
according to...

study?

“Social Cost-Benefit Analysis (SCBA) is an assessment method used
to determine the economic prudence of a project, programme, or
policy to all relevant members of society”. Critically examine this
statement.

Two methods can be used to produce expansion anchors. Method A
costs $80,000 initially and will have a $17,000 salvage value after
3 years. The operating cost with this method will be $38,000 in
year 1, increasing by $3600 each year. Method B will have a first
cost of $118,000, an operating cost of $6000 in year 1, increasing
by $6000 each year, and a $48,000 salvage value after its 3-year
life. At an interest rate of 10% per year,...

One of two methods must be used to produce expansion anchors.
Method A costs $75,000 initially and will have a $7,000 salvage
value after 3 years. The operating cost with this method will be
$36,000 per year. Method B will have a first cost of $105,000, an
operating cost of $7,000 per year, and a $46,000 salvage value
after its 3-year life. The interest rate for both the methods is
14%. Which method should be used on the basis of...

Two methods can be used to produce expansion anchors. Method A
costs $80,000 initially and will have a $14,000 salvage value after
3 years. The operating cost with this method will be $24,000 in
year 1, increasing by $2800 each year. Method B will have a first
cost of $104,000, an operating cost of $10000 in year 1, increasing
by $10000 each year, and a $34,000 salvage value after its 3-year
life. At an interest rate of 12% per year,...

Two methods can be used to produce solar panels for electric
power generation. Method 1 will have an initial cost of $580,000,
an AOC of $150,000 per year, and $170,000 salvage value after its
3-year life. Method 2 will cost $850,000 with an AOC of $170,000
and a $240,000 salvage value after its 5-year life. Assume your
boss asked you to determine which method is better, but she wants
the analysis done over a three-year planning period. You estimate
the...

One of largest banks in the country is researching the payment
method used by restaurant customers. The interest is to know if
customers have changed their method of payment with respect to
last year. As the statistician in charge of the analysis you
survey 220 restaurants and find historical information on payment
method as shown in the table below. Allow 5% of error when
performing the statistical test.
