Primary Materials

<p>The structural engineering community has a strong responsibility to contribute to a more efficient use of natural resources. Nowadays the construction industry is by far the most resource intense industry sector, approximately 40-50% of all primary raw materials are used, which raises the question about the architects and engineer’s accountability. In this context and as a result of the Paris Climate agreement the Dutch government defined the program “Nederland Circulair in 2050”, which states the ambition to use 50% less primary materials in 2030 and to have a full circular economy in 2050.</p><p>One possible approach to achieve these ambitious goals is the application of renewable, bio-based materials in the built environment and to replace traditional, typically cement-based, materials. Already in the past natural building materials, such as timber and bamboo have been used widely, but in recent years new materials came up and provide new opportunities to be used in the construction industry. The authors explored various alternatives, such as hemp and flax fibres, mycelium and lignin-based fibres for composite materials, which will be described with various experimental and realised case studies.</p>

Sustainable building design has become a hot topic over the past decades. Many standards, databases, and tools have been developed for achieving a sustainable building. Not until recently have the importance of structural engineering and its contribution to sustainable building design been full recognised. However, due to the highly fragmented and diversity of knowledge across building and infrastructure domains, there is a lack of approach that can address all the sustainable issues within the structural design. This paper reviews the sustainable design from the perspective of structural engineering: (1) reviewing the current situation; (2) identifying the gaps and difficulties; and (3) making recommendations for future improvements. The strategies and indicators, as well as BIM-enabled methodology, for sustainable structural design (SSD) are also discussed in a holistic way. The results of this investigation show that most of the methods are not doing well in terms of delivering a successful sustainable structural design. It is expected that the future BIM could probably provide such a platform to address these issues.

Ecological Remediation

Rapid industrial development and urbanization processes that occurred in China over the past 30 years has increased dramatically the consumption of natural resources and raw materials, thus exacerbating the human pressure on environmental ecosystems. An amount of damaged mountains and contaminated sites aroused rapidly so that ecological remediation for damaged mountains has become an urgent environmental issue in China. In this study, three points of damaged mountains in Jinan were chose to measure the combined approaches of ecological remediation. Phytoremediation for ecological restoration was employed under the assistance of lots of structural engineering measures. The obtained results indicated that a feasible solution always exists to solve the ecological remediation for the damaged mountains. Meanwhile, the approaches of remediation should fully consider their applicability to fit for the local situations. The remediation practice in Jinan can provide a successful case for other damaged mountains or contaminated sites.

The Gorgon Project on Barrow Island, located about 60 km from the northwest coast of Australia, was given the green light in September 2009. Construction and commissioning of the Gorgon LNG trains is limited to a 300 hectare development on a Class A reserve. Our commitment to the environment has driven our use of extensive modularisation to build the LNG trains. All of the major components have been pre-fabricated and assembled offsite into transportable parts,“ significantly reducing our footprint on the island. Subsequently the structural modules (including pre-assembled Piperacks) have undertaken a journey on a scale and complexity unmatched in the global LNG industry. The modules have been designed and built at diversely located engineering, fabrication and construction sites. These are then loaded out and sea transported from different international shipyards in more than 6. sea-transportation voyages, carrying more than 300 modules weighing more than 280,000 tonnes under constantly varying and hostile sea-faring conditions. The modules reach their final destination at Barrow Island to be installed without impacting the island’s uniquely treasured flora and fauna. These modules are designed to operate for its entire service life on cyclone-rated Barrow Island, which in the past has registered the highest ever wind gust of 408 kmph. Design and execution of the modules to sustain severe environmental conditions during its service lifecycle has been made possible by employing an innovative engineering mindset supported by robust structural methodologies to develop suitable facilities that can operate in a highly complex environment. This extended abstract showcases the structural engineering and execution methodologies that successfully overcame the challenging journey of the modules, thereby delivering a world class development co-existing with conservation in a pristine nature reserve on a very limited footprint.

The present Structural Engineering Document (SED) is a compilation of contributions devoted to the vast topic of history of structural engineering as well as interventions on heritage structures and structures of high cultural values. Various, some-times opposed, viewpoints and approaches are expressed and presented. The rather heterogeneous and controversial nature of the content of this SED shall stimulate lively discus-sions within the structural engineering community who needs to increase the awareness of historical and cultural aspects of structures and structural engineering. Current structural engineering methods and practice are only at the very begin-ning of effective engineering, really integrating historical and cultural aspects in the assessment of existing structures and in intervention projects to adapt or modify structures of cultural values for future demands. Knowing the past is indispensable for modern structural engineering!

Research Endeavor

Sustainable building design has become a wide and multidisciplinary research endeavor including mechanical, electrical, electronic, communication, acoustic, architectural, and structural engineering. It involves the participation of owners, contractors, suppliers and building users. There has been a lot of talk about sustainable buildings in the past few years. Most of the published research is concerned with saving energy and water and making the buildings more environmentally friendly by, say, reducing the carbon emissions. In this article, sustainable building design is reviewed from the viewpoint of structural engineering. Different strategies presented in the literature are summarized. Finally, the authors argue that the next big leap in sustainable building design should come from the integration of the smart structure technology including the use of hybrid and semi-active vibration controllers that can result in substantially lighter and more efficient structures.

Strain Responses

Abstract Over the past decade, shape memory alloy (SMA) in the form of wires and cables have been extensively studied for various structural engineering applications. There are numerous application areas where pure compression (or coupled with tension) is the primary load bearing scenario, which requires larger size SMA bars. However, the compression behavior of SMA bars is not well known, and little is reported in the literature. In that perspective, this paper presents an experimental study on large diameter superelastic Nickel-Titanium (NiTi) bars subjected to a cyclic compression load. A total of nine SMA bars having slenderness ratios ranging from 60 to 90 were tested. Hysteretic stress-strain responses are plotted and critical buckling load, energy dissipation and residual strain of SMA bars with different slenderness ratios are presented.

The results of a comprehensive research program on tsunami-induced forces on infrastructure located in coastal areas are presented. This research project is the result of an extensive interdisciplinary project (coastal and structural engineering) which spanned over the past five years and which included several field data reconnaissance missions, as well as analytical, experimental and numerical modeling of the extreme hydrodynamic forces on buildings and their component structural elements. The purpose of this research and engineering project is to elucidate the complex hydrodynamic mechanisms of the impact and extreme loadings on buildings and to properly quantify loads and further propose and derive new formulations for the design of structures located in the vicinity of the shoreline in tsunami-prone coastal areas.
