What is a portal frame structure?
Portal frames are a type of structural frame, that, in their simplest form, are characterised by a beam (or rafter) supported at either end by columns, however, the joints between the beam and columns are 'rigid' so that the bending moment in the beam is transferred to the columns.
What is a concrete frame structure?
A concrete frame is a common form of structure, comprising a network of columns and connecting beams that forms the structural 'skeleton' of a building. This grid of beams and columns is typically constructed on a concrete foundation and is used to support the building's floors, roof, walls, cladding and so on.

What is the weakest part of a frame structure?
The foundation is the weak point in the building's structure because it does not carry any weight. It spreads out the load from the building above it so that it does not have to bear the whole weight of the house.
