Assignment Brief and Guidance: Beam $3$ will be designed to carry loads as following:

uniformly distributed dead load of $2k\frac{N}{m}$ including beam weight over the length

of the beam.

uniformly distributed live load of $1$ KN over the length of the beam.

take the effect of rain load and wind load on this beam to be uniformly distributed loads

of $2k\frac{N}{m}$ over the length of the beam.

Safety factors for live loads, dead loads, and imposed loads must be taken into

consideration when analyzing the above beams. These safety factors will be

determined according to "ASCE$-98$ code" and $"$EN $1993$ Eurocodes$3$ "and

"ANSVAISC $360-16$ Specification for Structural Steel Buildings" regulations.

For the analysis reason your manger gives you the following column$(1,2,3)$

section to be reinforced section or steel section $,$ for Reinforced section using

the ratio of reinforced to be $1\%$ and the steel section to W$10$X$22$ the length of the

column is $3\mathrm{.}25$ m $,$ figure $(4)$ shows the section in columns.

Fig. $(4)$ : Section in columns

Your manager gives you a suggest about a column supporting system as

showing in figure $(5)$ for the column $1,2,3.$

Fig. $(5)$ : Supporting for columns

Used the following data in your calculation and studies for the project :

Concrete Compressive Strength $(Fc)$ is MPA

$1-$ Yield strength for reinforced steel is $414$ MPA $2-$ Yield strength for Steel is $50$ Ksi

$3-$ The project area has a high humidity value

$4-$ According to the geotechnical engineer the soil of the project has a high

value of sulfate

Task $1$

your manager wants to use a modern way in construction for the villa. The manager

asked you to perform the following tasks in order to determine the forces and moments

in the given beams to be designed later.

From the load combination equations that includes the safety factors for the dead

loads, live loads, and imposed loads that you will determine from the given

codes and regulations given in the scenario produce appropriate factors of

safety for the loads given in the scenario for each beam used the code that

mention in the scenario $,$ determine the value of ultimate load using appropriate

safety factor combination to continue the analysis for the beams mention before.

discuss the safety requirements for choosing these factors in your structural

designs for each beam $,$ your discussion must include the following

$1-$ the importance of the safety requirements which include the design of fire

conditions and corrosion effects to ensure safe design.

$2-$ the differences and relationships between the requirements for each code

and regulation.

calculate shear forces and bending moments for beams $1,2,$ and $3$ and produce

shear force and bending moment diagrams for each beam.

after you done with your calculation for bending moments and shear $,$ using

ASCE$-98$ code and EN $1993$ Eurocodes $3$ and ANSI$/$AISC $360-16$ Specification

for Structural Steel Buildings, your manager asked you to Evaluate the safety

and economics reason of using maximum bending moment method to determine

the steel beam section dimensions in the design process by showing:

$-$The advantages and disadvantages for using this method.

$-$The significance of selecting the section according to this method.

Arab Construction Company $($ACC$)$ is a renowned construction company in Amman$-$

Jordan. It is specialized in broad types of construction and complex buildings. It has

attained recently a new project. The project is a modern villa which includes steel and

concrete members as shown in the sketch below $($Figure $1)$

Fig $1$: $3$D Villa Sketch

This project is given to your company from another company in order to help them in the

analysis and design of steel and concrete beams and columns in this villa as shown

below $($Figures $2$ and $3)$
