Dear fellow engineers, In a refugee camp reconstruction, we have the following dilemma: First, we have an existing retaining wall, height up to 4.5 meters, thickness ranging from 0.25 to 0.4 m. On the back of the wall we have existing an layer of cyclopean concrete :height up to 4.5, width... -
Assalamu Aalikum, Hi, I am a new member. I have a plot measuring 30*70 feet. Most of houses being built here (in Rawalpindi) have masonry foundations (a pyramid of bricks on PCC or sometimes the PCC layer has three to four iron rods of size 3/8 or 4/8 in this "PCC" layer. I want to make a raft... -
From engineering point of view, it is really very amazing to see a complete city builtup in water ways, in a lagoon. How did they make the foundation system of buildings completely all the time underwater? Really interesting article here is. It also explains some modern challanges to the city i.e. f...

High Loads under Columns and Bearing Capacity Failure
muneeb1213 posted a topic in Foundation Design
I m designing a 4 storey building on a poorly graded sand with SPN value of 5 and allowable bearing capacity of 0.5 tonn/sq.ft..... for the mat foundation, i provided beams of 18 x 36 and mat thickness as 24 inches ... however the soil pressure are still above safe bearing capacity.. My question is... -
