Photovoltaic panel purlin reinforcement method

What is steel purlin reinforcement technology?

Such a reinforcing technology has a good reinforcement efficiency in terms of flexural stiffness of the steel purlin (i.e., ratio of the external loading to the purlin deflection in the elastic stage) and is convenient to construct without using hydraulic jacks.

What causes a pre-camber deflection in a steel purlin?

The reinforcement by prestressed CFRPs led to precompression of the lower flange and pretension of the upper flange of the steel purlin, thus causing a pre-camber deflection in the purlin; that is, there were 1.2 mm and 1.4 mm upward deformations in the midspan of C-PS and Z-PS, respectively.

How does a prestressed CFRP affect the flexural behavior of a purlin?

Based on the above two aspects, the prestressed CFRP can delay the local buckling or yielding of the upper flange and the distortional buckling of the purlin. Third, the steel hoops of the anchorage and prestressing chair can further reinforce the web of the purlin, thus increasing its flexural behavior.

How do you anchor a steel purlin?

First, the anchorages at both ends fix the ends of the CFRP to the ends of the steel purlin by using high-strength bolts, U-shaped steel hoops and adhesive. Specifically, the U-shaped steel hoop has 8 holes corresponding to 8 bolts and is wider than the CFRP, so the bolts will not go through the CFRP. The anchoring procedure is shown as follows.

Can solar photovoltaic panels be installed on roof of existing industrial building?

harnessed without the release of harmful pollutants to the environment. In our study solar photovoltaic panels are fi ed on roof of existing industrial building in Kolar district Karnataka. The main purpose of the analysis is to decide the structural sections and conn

Does fluencing increase/decreasing in moment of inertia of a purlin section?

fluencing in increasing/decreasing in moment of inertia of the section. The moment of inertia of the section is the resulting parameter which decides the stability of the type and profile of the purlin section.The study indicates that p rlin with higher moment of inertia has better moment carrying capacity. The U-Purlin
