This research aims to deepen the knowledge of the interactions between the building envelope and the surrounding environment, with a focus on the influence of solar radiation variation on structural steel. Through an in-depth analysis, the aim is to develop predictive models to assess the impact of thermal stress, in terms of increasing the tensional state in structural elements, useful for proposing optimised design solutions.
To carry out this analysis, the structural modelling and calculation software RFEM6 was used, which allowed the application of the thermal load to the façades of the high-rise building directly exposed to sunlight, thus enabling the evaluation of the effects these caused on the individual elements and consequently on the entire structure.
The paper is divided into several parts: i) a state of the art on tall structures; ii) a focus on what are the current issues concerning this type of building; iii) a presentation, modelling and analysis of a case study; iv) and finally the results of the simulations with discussion.
The simulations conducted have shown that the thermal loads induced by solar radiation are capable of producing an impact on the structure comparable to that of traditional static or dynamic loads, and that it is therefore essential to consider them in the design phase.
