Single box girder bridge , flyover above eastern approach of the San Francisco–Oakland Bay Bridge. A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete.
A hot-rolled HSS-box section cut open with a bandsaw, demonstrating residual stress. A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology.
In solid mechanics and structural engineering, section modulus is a geometric property of a given cross-section used in the design of beams or flexural members. Other geometric properties used in design include: area for tension and shear, radius of gyration for compression, and second moment of area and polar second moment of area for stiffness .

Section Beams are made of steel and they have a specific lengths and shapes like Ɪ-beam, 'L', C-channel and I flanged beam. These types of section are usually used ...
The Euler–Bernoulli beam equation shows that the Ɪ-shaped section is a very efficient form for carrying both bending and shear loads in the plane of the web. On the other hand, the cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often ...
One of the more natural choices is the box topology, where a base is given by the Cartesian products of open sets in the component spaces. [1] Another possibility is the product topology , where a base is also given by the Cartesian products of open sets in the component spaces, but only finitely many of which can be unequal to the entire ...
An electrical junction box (also known as a "jbox") is an enclosure housing electrical connections. [1] Junction boxes protect the electrical connections from the weather , as well as protecting people from accidental electric shocks .
