In this document, target displacement calculation for nonlinear pushover analysis according to FEMA 356 3.3.3.3.2 will be explained in detail and verified with the hand calculation.

This document will explain target displacement calculation for nonlinear pushover analysis according to EC8 Annex B in detail and verified with the hand calculation.

Traditionally, continuous beam lines are analysed and designed in isolation. The modelling of the support conditions in such cases is often unsophisticated or simplified. For example, in the analysis of secondary beams supported by primary beams, the traditional method is to perform 2 analyses independently & separately.

ProtaStructure checks global and local ductility conditions according to ACI 318 18.7.3. This document covers the calculation details of the strong column - weak beam condition checks.

ProtaStructure checks the beam-column joint shear limits according to ACI 318-19 Chapter 15 and 18.8.4. In this document, calculation details about beam-column joint shear are explained.

ProtaStructure checks the beam-column joint shear design considerations according to EC8 Chapters 5.5.2.3 and 5.5.3.3. In this document, calculation details about beam-column joint shear are explained.

ProtaStructure checks global and local ductility conditions according to EC8 Chapter 4.4.2.3. This document explains calculations for strong column weak beam condition checks.

Many structures will undergo a natural sway under purely vertical (gravity) loads. These sways can sometimes introduce significant changes to the expected moment diagrams in beams.

The axial force & moment of the columns and walls can also be significantly changed due to sway.

In such cases, it is important to ensure that checks are made for combinations where notional load cases are applied in sympathy with the natural sway of the structure.

This design guide discusses the Beam Design to Eurocode 2 Design Code BS EN 1992-1-1:2004. 

Users who wish to understand the analysis and design calculation for storey beams, are recommended to read this document. 

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.
