Obliczenia uproszczone for Overturning andd Lateral Stabilny Of Shallow Fundacje

Shallow foundations are common use in construction to transfer loads from structures to thee ground. Ensuring their ir stability against overturning and d lateral movement is essential for safety and durability. Simplified calculation methods provide e quick assessments to determinae if a foundation is stable undependted loads and conditions.

Overturning Stability

Overturning występuje, gdy po stronie siły, such as wind or seismic activity, create moments that the resisting moments of thee foundation. Toevatate overturning stability, the following simplified approach is used:

Obliczenie te overturning moment (M is 1; Xi1; FLT: 0; Xi3; o Xi1; FLT: 1 X3; Xi3;) caused by y lateral forces andd compare it to thee resisting moment (M Xi1; Xi1; FLT: 2 XI3; XI3; r Xi1; FLT: 3 XI3; XI3;) provided the weight of the structure and foredation. The safety factor (SF) is given by:

SF = M = 1; Xi1; FLT: 0 Xi3; Xi3; r Xi1; Xi1; FLT: 1 Xi3; Xi3; / M Xi1; Xi1; FLT: 2 Xi3; Xi3; Xi3; Xi3; Xi3;

If SF is greater than 1.5, the foundation is considered stable against overturning.

Stabilność Lateral

Lateral stabilizacyjny involves resisting horizontal forces that could cause sliding or shifting. The main considerations included thee frictional resistance and thee passive earth pressure.

Te proste obliczenia involves porównają te poziomy siły (H) te maksymalne siły rezystywne (R). Te siły rezystyngu is often estimated as:

R = cN + qN tak

Gdzie?

If thee horizontal force H is less than R, thee foundation is considered stable against sliding.
