$\backslash$Problem:

A proposed elevated concrete water tank is shown on the plan below. The tank serves as a water

supply for a local subdivision and distributes it via gravity due to its elevation. The properties of the tank are as follows:

ALL. GIRDERS$/$BEANS $-300$x$800$m

AL$.$

SI$.$AD $-200MM$ THICK

Properties of the tank:

The walls are made of $250mm$ thik concrete that is $5\mathrm{.}6$ meters high which is carried by the girders and

beams. The maximum height of the waler on each chamber is limited by placing a pipe $0\mathrm{.}6m$ below the

lop that would aulomatically ist the water overflow to the next chamber. When all chambers are filled.

the waler overflows to the last outlet pipe that will then serve the subdivision. Ignore the weight of the

slab cover on top.

Parameters:

$fc=4000(28$Mpa$)$

$fy=60,000(414$Mpa$)$

$E($ steel $)=29,000$ksi$(200,000$Mpa$)$

Density of water $($specific weight$)-9\mathrm{.}81k\frac{N}{m}3$

Density of concrele $-24k\frac{N}{c}$ubic meter

QUESTIONS

Determine uniformly distributed load to be carried by the girdars along Gridline $B$ tue to DEAD

LOAD.

Determine the uniformly distributad load to be carriad by the girders along Gridline $B$ dua to LIVE

LOAD.

If the beam along gridline $B$ is considered a beam with spandrel support at its ends, $5$

determine the negative Moment at Gridline B due to Dead Load

Using the same scenario for Question $3,$ determine the negative Moment due to Live Load
