$(1)$ Set up the following action, in term of uniform distributed load $($UDL$)$ along the beam $($characteristic value$)(5$ points$)$

$(1\mathrm{.}1)$ Structural Dead Load Concrete weight $=25$kN$/$m$3$

$(1\mathrm{.}2)$ Slab Concrete weight $=25$kN$/$m$3$

$(1\mathrm{.}3)$ Asphalt unit weight $=23$kN$/$m$3$

$(1\mathrm{.}4)$ Live Load Pressure $=5$kPa

$(2)$ Set up an appropriate load combination for SLS $($construction and operation$)$ and ULS

$($operation$)$ for design based on your result above and the information provided under the

section of Design Basis. $(5$ points$).$
