Constructing buildings are easy but strong base are not the thing that everybody cares for. Though it is the thing to care for, it is found to be ignored most of the times. Most often we get to hear that in so called place so called building collapsed. Is it good news to hear such incident? It is not, right? But also most of the builders do not apply best measures to prevent from such circumstances. But there are some of the industries that help to build best of the construction.
Nowadays, new technique called Portal frame is being used to prevent from uneven situations. It is a method to build, construct and design the structures by reinforcing steel concrete materials in the construction process. Though they can be constructed with the help of laminated timber they are reinforced with concrete materials. These steel framed portals help to carry the bending forces by making connections between the rafters and the columns. They are designed in such a way that they act as the moment resistant
The portal frame has very strong joints and is placed to fix the materials at a place. The bending moments that happen in the rafters are transferred to the columns with the help of these frames. The size of the rafters can be reduced and the span can be improved for increasing the span as well making it a very effective construction technique.
