“…However, the web crippling response of web perforated lipped CF aluminium sections has been rarely studied. Identifying this research gap, Alsanat et al [86] investigated the web crippling behaviour of lipped CF aluminium sections with circular openings, under ETF loading conditions. Nonetheless, the web crippling behaviour of web perforated lipped CF aluminum sections under ITF, IOF, and EOF loading conditions are yet to be explored.…”

“…Considering the strain hardening nature of CF aluminium, Continuous Strength Method (CSM) was applied to model the material behaviour of CF aluminium sections. In this study, similar material properties were considered for the whole model, despite the variation of the material properties at corners of the LCS due to the plastic deformations caused via the cold working process [58,86].…”

“…Past experimental data on the web crippling behaviour of lipped CF steel, stainless steel, and aluminium sections under ETF loading condition were considered in validating the developed FE model. Test data on the web crippling response of web perforated lipped CF steel (reported in [58]) and aluminium (reported in [86]) channel sections subjected to ETF loading were respectively used in validating the models developed for CF steel and aluminum materials. Considering the unavailability of experimental test data CFSS channel sections, web crippling test data of web perforated lipped CFS channel sections under ETF loading (reported in [58]) were used to validate the model developed for CFSS sections.…”

This paper reviews the research advancements and design practices related to the structural web crippling response of lipped Cold-Formed (CF) carbon steel, stainless steel, and aluminium channels with web perforations. The web crippling response differs among each material based on the non-linear stress-strain characteristics and degree of strain hardening. Therefore, the reduction in the web crippling strength of web-perforated CF channel sections made of different materials may not be equivalent. The research activities surrounding the web crippling response of CF channels with and without web openings were reviewed initially. Despite the limited design provisions given in the international specifications for the web crippling design of lipped CF channels with web openings, web crippling studies conducted across the world have developed suitable design equations in the form of reduction factors. Past research studies have substantially captured the web crippling response of carbon steel channels with web openings while that of stainless steel and aluminium are limited, as identified in this paper. Lastly, numerical models were developed for simulating the web crippling behaviour of lipped CF carbon steel, stainless steel, and aluminium channels with web opening and validated with past experimental data, with a view for developing unified design guidelines.

“…For example, when the wood is chopped, the fibres shorten, whereas recycling steel keeps all of its qualities on a molecular level, offering greater robustness [49]. Steel constructions also require less maintenance because they are not affected by moisture or biological activity [50][51][52][53][54][55][56][57][58]. Hence, steel was chosen as the material of study in this paper to help fill this research gap and contribute to the proposed repository.…”

This research undertakes a Life Cycle Analysis (LCA) to determine the climate change potential of a typical newly built steel detached dwelling in Palmerston North, New Zealand (NZ) and assesses its results concerning the 2 °C and 1.5 °C 2050 Paris Agreement targets. The proposed, upcoming policy and actions of the NZ government relating to its residential building and construction sector, which are set with an overarching aim to allow NZ to progress towards meeting the 2050 Paris Agreement targets, are also discussed in this paper. The results of the LCA demonstrate that the projected stock of steel-framed detached houses significantly exceeds the calculated climate budget and eventual 2050 Paris Agreement targets. For both the 2 °C and 1.5 °C scenarios, the magnitude of exceedance of the climate budget is 5.2 and 7.3 times more than the acceptable limit, correspondingly. These findings suggest that the sector will need to undergo a significant transition in order to fulfil the 2050 Paris Agreement targets. In the meanwhile, the sector’s upcoming policies and regulations must be achievable while progressing toward achieving net-zero carbon emissions.
