Utilising the stiffness of nominally pinned bases in frame design
Posted on in MasterFrame
Typically a four-bolt column base is usually considered to be a nominally pinned support in structural analysis. However, benefit can be taken from the stiffness of nominally pinned bases to reduce frame deflections and to reduce the effects of the deformed geometry.

Gain a competitive edge in structural design using cellular beams
Posted on in Steel Design
The popularity of cellular beams has been rapidly increasing in recent decades for many building types. Beyond the aesthetic fashion for cellular beams, they have many advantages for a building project.

Join us for our next Webinar and learn how to design composite floors and stairs for vibrations using state-of-the-art and accurate finite element based vibration analysis and design.
Pile cap design using Strut and Tie methodology
Posted on in Pile Cap
For pile cap design, two methods are commonly used: design using beam theory or design using strut and tie method. In the first case, the pile cap is handled as an inverted beam and designed like a beam for bending and shear. But how can we design the pile cap, if the beam theory is not applicable?
How to model multi-storey masonry walls?
Posted on in Masonry
Masonry is the most common construction type for low-rise residential buildings. At first, the modelling of a simple masonry wall looks very simple. But what is the situation in the case of a multi-storey masonry wall?
The effect of fastener holes' on the design resistance of steel members
Posted on in Steel Design
To form structural steel joints, in most cases, we use bolts and fasteners, which require holes in the steel members. How can we take into account the effect of fastener holes in the steel member design?
Comparison of the first- and second-order analysis and the possible effects of the deformation on the analysis results
Posted on in MasterFrame
Modern design codes provide several analysis options to determine the structural deflections and internal forces for dimensioning. These codes define certain usable boundaries, but between them, it is more or less the choice of the engineer which method is the most suitable to the actual design situation. In engineering practice, for building structures, the only analysis types that are likely to be used are first-order (linear static) analysis and second-order (P-delta static) analysis.
How can we determine the sensitivity of a steel frame to second-order effects to Eurocode?
Posted on in MasterFrame
According to Eurocode 3, if the deformed geometry significantly modifies the structural behaviour we have to take into account the influence of the deformation in the analysis. But how can we determine that our structure is sensitive for deformation or not and if it is how can we take into account during the analysis?
Optimisation of Steel Moment Connections
Posted on in Connections
Steel connections are built up from several components from which the weakest one defines the capacity. There could be many connection configurations which are proper for our design situation, but how can we find the most economic one or which pass the design and/or the manufacturing requirements.
