This design guide discusses the Differential Axial Deformation Effect (DADE) of columns and walls due to 3D analysis of multi storey buildings. 

The methods to reduce this effect using stiffness adjustment (Area Factor) & FE Floor Analysis are explored. 
Users who find unexpected force diagram of a multi-storey building, especially bending moments in top storey beams, are recommended to read this document. 

ProtaStructure’s punching shear check is an interactive design tool. You need to use it carefully on one column, or a group of the similar column(s) at a time to review/establish the correct design settings. Having done so rechecking can be carried out in a more automatic fashion.

In this design guide, we will show what this check can do for you, and illustrate the scope & limitations of which you need to be aware.

In this document, calculation and decomposition of loads on ribbed and waffle slabs are explained.

Modeling and design of ribbed and waffle slabs are out of the scope of this document.

In this document, pad footing design in accordance with TS500 is explained. An arbitrary pad footing is selected and it is designed under a single load combination.

Check this article on the sign of the results after response spectrum analysis and different options to work with them.

In this case study, the equivalent lateral forces acting on a 4 story residential reinforced concrete building is determined using the procedures described in International Building Code 2018 (IBC 2018).

In this case study, the equivalent lateral forces acting on a 4 story residential reinforced concrete building is determined using the procedures described in the 1997 Uniform Building Code (UBC 97).
