Model for alkali-silica reaction expansions in concrete using zero-thickness chemo-mechanical interface elements

Alkali-Silica Reaction (ASR) is a particular type of chemical reaction in concrete, which produces cracking and overall expansion of the affected structural element due to the formation of expansive reaction products within the cracks. This paper develops the formulation of a coupled Chemo-Mechanical (C-M) Finite Element (FE) model for...

From sequentially linear analysis to incremental sequentially linear analysis: Robust algorithms for solving the non-linear equations of structures of quasi-brittle materials

It is difficult to accurately predict the strength of masonry and concrete structures. The most widely used method for simulating their behaviour is finite element analysis with the Newton-Raphson method and arch length control. However, the Newton-Raphson method can diverge and not produce a result, for example in bifurcations or during snap...

3D Concrete Printing for Structural Applications

Recent years have seen a rapid growth of additive manufacturing methods for concrete construction. Potential advantages include reduced material use and cost, reduced labor, mass customization and CO2 footprint reduction. None of these methods, however, has yet been able to produce additively manufactured concrete with material properties...

CAST Formwork System: A redesign and evaluation of the CAST formwork system concept

In the graduation project of Remmerswaal, N. (2015), a concept for a new building system for the Indonesian kampung was developed: The CAST formwork system. The development of the concept was based on several identified problems of the Indonesian construction sector. The project concluded with a first design of the CAST formwork system, in this...

Concrete walls: The evaluation of the reinforcement design methods in D-regions around openings and overhangs

Unlike for concrete beams and plates, relative little amount of theory is present for concrete walls. In combination with the underexposure of the reinforcement design of D-regions in the codes when concrete walls are considered, engineering companies struggle to find a clear reinforcement design procedure which is agreed upon by all relevant...
