Theoretical calculation formula for photovoltaic bracket U-shaped steel

How do you calculate the stability of a steel sheet pile?

The specific calculation method is as follows: Firstly considering the standardized stability calculation method, take the center coordinates of the standard U-shaped steel sheet pile (referred to as the standard member) as the coordinate origin, and establish the x1–y1 rectangular coordinate system (as shown in Fig. 1).

How to calculate critical buckling load of a stifened plate?

Assuming that local stifening is adopted and the spacing between the stifened plates is b0, the critical load calculated ( n · b0 = l ) is equal to the critical buckling load calculated by the specification for full-length stifening. Definition and calculation method of position function. Layout of the Position function of a stifened plate.

What is the critical buckling load of a steel sheet pile?

Taking a stiffened plate arranged with a 10 m long AU18 standard steel sheet pile as an example, the critical buckling load values of unstiffened and full length stiffened steel sheet piles calculated are 1216kN (N 1max) and 1828.16kN (N 2max ) respectively (as shown in Table 2 ).

Does the steel structure specification code calculate the ultimate load of usssps?

Currently, the steel structure specification code lacks a theoretical calculation approach for the ultimate load of USSSPs for stiffening plates. This article considers the size and stiffening position effects of the stiffening plate during the partial stiffening arrangement.

Are ground mounting steel frames suitable for PV solar power plant projects?

In the photovoltaic (PV) solar power plant projects, PV solar panel (SP) support structure is one of the main elements and limited numerical studies exist on PVSP ground mounting steel frames to be a research gap that has not be addressed adequately in the literature.

What is the stifness reduction factor of steel sheet piles?

Also, a finite element model of steel sheet piles was developed considering the interaction between the locks, and concluded that the stifness reduction factor in the actual engineering design should not be less than 0.5, otherwise the impact of the locks on the support structure of the steel sheet pile will be exaggerated7.
