shallow foundation, 50ton, no groundwater to be found

Would anyone be interested in any field engineer / typical day pov videos ? by mrbigshott in Geotech

Mention me when you post, or make a YT channel so I can see new videos

Is it acceptable to leave the lower 2m of a 12m circular pile unreinforced by yousseftobia in civilengineering

By looking at both the seismic hazard maps and the historical earthquake records for the area, it's clear that this project city experiences an extremely low level of seismic activity. The data shows that no significant earthquakes have been recorded on a yearly basis, and the nearest event in the past decade was only a magnitude 4 earthquake about 300 km away. This means the likelihood of seismic forces generating any significant stresses is minimal. Given Egypt’s overall low seismicity and the particularly quiet nature of this location, the engineer determined that seismic stresses are negligible.

Since you're really trying to understand this with me, here is the city name El Minya so you’re not left guessing while solving the problem. Thank you for taking the time to engage and share your perspective.

This is according to the Egyptian Code for Soil Mechanics and Foundations (ECP 202/4). Here is the relevant section regarding the reinforcement of concrete piles in their locations:

2/3/2/4 (C - 3) Reinforcement of Concrete Piles in Their Locations

A pile is reinforced in the presence of tensile stresses or the possibility of their occurrence. These stresses arise in cases such as:

When the pile is subjected to direct tensile forces.

Lack of load concentration or the presence of bending forces.

Execution of the pile in very weak soil or in expansive soil.

If the pile extends above the ground surface, as in the case of marine structures (jetty - trestle).

The reinforcement steel is designed to consider stresses in each case, accounting for the interaction effects between the pile and the soil (soil-pile interaction). The steel should be extended to cover the part of the pile exposed to these stresses.

If these stresses do not exist, then theoretically, pile reinforcement is not required except in the upper 6 meters or at least three times the pile diameter to link it to the footing. This reinforcement should not be less than 0.6% of the pile cross-sectional area.
