Designing Sign Structure on the NJ Turnpike

How to design a sign structure on the NJ Turnpike to resist wind force?

What are the soil conditions for the design?

Designing a Sign Structure

To design a sign structure on the NJ Turnpike to resist wind force, we need to consider the moment produced by the wind force, axial load, and soil conditions. The moment is given as 25 k-ft in one direction, and the axial load is 30 kips.

Soil Conditions

The soil conditions consist of a normally consolidated clay layer with properties such as unconfined compression strength (su) of 800 psf and saturated unit weight (γsat) of 110 pcf.

Designing a Sign Structure to Resist Wind Force

When designing a sign structure on the NJ Turnpike to resist wind force, it is crucial to calculate the moment produced by the wind force and the axial load acting on the structure. By considering these factors along with the soil conditions, we can ensure a safe and stable design.

Soil Conditions

The soil conditions play a significant role in the design of the sign structure. The properties of the soil, such as the unconfined compression strength (su) and saturated unit weight (γsat), provide essential information for calculating the bearing capacity and stability of the structure.

By analyzing the soil conditions and applying the appropriate design factors, we can create a sign structure on the NJ Turnpike that is capable of resisting wind forces and ensuring the safety of the structure.
