Due to the safety awareness arisen from natural and human-caused disasters, robustness design of building is increasingly important to ensure the stability of the building and to prevent progressive collapse. For this reason, the robustness design of innovative construction technologies such as modular construction may be essential due to its relative novel structural form and numerous joints among modules. Particularly in Singapore, Prefabricated Prefinished Volumetric Construction (PPVC) has been highly promoted in residential and commercial buildings, hostels and hospitals to boost the construction productivity and quality as well as to reduce the reliance on foreign workforce. PPVC offers high quality and efficiency because most of the finishes and mechanical and electrical services are manufactured and installed together with the modules in factory, before sending for on-site assembly. To maximize the productivity of PPVC, modular design standardization and repetition can be improved by going for high-rise. Nonetheless, there are limited studies on the robustness of PPVC high-rise building and its behavior under progressive collapse remains uncertain. Therefore, this paper investigates the robustness of steel PPVC high-rise building under column removal scenarios by conducting non-linear numerical analysis. The effects of joint design and diaphragm action between modules are studied to ensure continuity of horizontal and vertical tying. This paper provides insight on the behaviour and alternative path for load transfer under column removal scenario for future design guideline of robustness PPVC building.

And Performance

Noticeably, the design of today’s building particularly high rise building and skyscraper show irregularity in both horizontal and vertical direction which is dangerous for each element inside the building. Handily, certain disjoint can be applied to the building to minimize the irregularity for better desired behaviour. Dilatation is a well-known method together with several other methods are introduced and implemented for gaining principal of simple regular building. Double column and cantilever beam method are two of them which are excellent to divide the building into several regular buildings after they are applied. The double column is found out to perform better on dilatation direction application at the weak axis of the building. Moreover, accurate review of double column distance will solve the load transfer discontinuity so that better behaviour and performance can be satisfied. Hereinafter, the cantilever beam conducts perfectly when the shear wall is sufficiently installed and the cantilever beam span is contently fulfilled. Shear wall remarkably contributes to enhancing the behaviour and performance of the structure as the shear wall placement is proper to absorb seismic lateral force. Recommendation of both systems can be well performed once the column distance, cantilever span, and shear wall installation are strongly taken into consideration.

Building progressive collapse is currently one of the hottest topics in the structural engineering field. Most of the research carried out to date on this topic has been focused on the structural analysis of the failure of one or more columns in a building to determine the Alternative Load Paths (ALPs) the structure can activate. Past research was mainly focused on extreme situations with high loads and large structural deformations and, to a lesser extent, research looked at lower loads used in design accidental situations, which requires a different set of assumptions in the analysis. This paper describes a study aimed at analysing accidental design situations in corner-column removal scenarios in reinforced concrete (RC) building structures and evaluating the available real ALPs in order to establish practical recommendations for design situations that could be taken into account in future design codes. A wide parametric computational analysis was carried out with advanced Finite Element (FE) models which the authors validated by full-scale tests on a purpose-built building structure. The findings allowed us to: (i) establish design recommendations, (ii) demonstrate the importance of Vierendeel action and (iii) recommend Dynamic Amplification Factors (DAFs) for design situations.

Structural Concept

In the article there will be a consideration of collapse process progressive simulation of a high-rise building by removing the first-floor columns. The object of the study will be a 27-storeyed high-rise building. The high-rise building structural concept will consist on a monolithic reinforced concrete frame. The mounting base structural concept has been modeled as absolutely rigid. Static and dynamic calculations have been performed in the «Ing +» software complex, while the wind load pulsating component was taking into account using the finite-element method for the spatial slab-and-rod model. The dynamic calculation analysis has shown the obtained oscillation forms corresponding to the design requirements. The stress-strain behavior has been studied for the floor slabs as reinforce constructive of a typical floor. Structural concepts for the building frame of a high-rise building have been developed to reduce the progressive collapse risk. In the physically non-linear calculations, with the removal of the first-floor corner and central columns, four options for the sandwich floor slabs reinforcing were taking into account. The rational reinforcement option has been selected, in which the building is resistant to progressive collapse. The building frame structural concept with the floor slabs heavy-duty reinforcement of the first five floors has been suggested. An outrigger floor with encircling reinforced concrete trusses along the outer contour was included to reinforce the load-carrying framework. Recommendations on the choice of rational structural concepts, reducing a high-rise building progressive collapse risk have been given.

Mass Timber

Due to the inherent inefficiencies in conventional approaches followed in the construction industry and the global demand for lean and sustainable construction techniques, modular construction has witnessed a resurge especially in high-rise buildings. As such, much efforts have been put in studying the use of mass timber for the main structure of high-rise buildings in order to ensure more sustainable developments with high levels of adaptability. In this regard, previous research efforts have primarily focused on the added benefits of mass timber, its structural design and performance, and associated safety requirements. However, owing to the novelty in combining modular processes with timber materials and associated lack of data, several regulatory barriers and contractual issues still exist. To mitigate these issues, this paper studies the specifics of permit approvals and contracting issues in timber high-rise modular buildings. The objective is to develop a comprehensive up-to-date review and analysis of the relevant practices and to conduct interviews with industry experts to analyze their concerns, given the insufficient number of guides and building codes that dealt with these issues. Hence, our study investigates the process of obtaining permit approvals from local jurisdictions in Ontario in addition to the requirements for submission of additional documentation, engineering analysis, and testing. Moreover, it analyzes the initial stage of contractual agreement of stakeholders under the uncertainties imposed on these buildings and evaluates the suitability of Integrated Project Delivery (IPD) contracting method. Presenting detailed analysis of the initial planning stages for timber high-rise modular buildings can in turn suggest the best practices to be taken into consideration for the successful implementation of these buildings under the current building code.
