Poston, Randall W.; Dolan, Charles W. | Reorganization of the ACI 318 Building Code | Structural Concrete | 2/2011 | 126-128 | Articles |
KurzfassungIn 2008, ACI 318 initiated a six-year task of reorganizing the format of the ACI Building Code for Concrete Structures. This is the first major reorganization of the code in nearly 40 years. The reorganization effort moves the code from a behaviour-based to a member-based design approach. This article presents the philosophy of the code development, efforts leading up to the reorganization and an outline of the 2014 code format. x | |||||

van Breugel, Klaas | Structural systems for protection against extreme events | Structural Concrete | 1/2011 | 5-12 | Articles |
KurzfassungTypical for extreme events is their multidisciplinary nature, and, consequently, solutions for protection against extreme events should mirror their inherent characteristics. This article discusses different types of hazards and extreme events in order to illustrate the complexity and scale of the problem. Concepts for judging hazards and associated risks are dealt with. Some features of the traditional risk concept are discussed, followed by a proposal for an extended risk concept, to be applied when dealing with extreme hazards. The emphasis will be on aspects that are typical of “low-probability/high-consequence risks”, particularly industrial risks. The potential role of structural (concrete) protective systems for mitigating the consequences of industrial accidents is emphasized. Throughout this article, the role of structural designers and their possible contribution to the debate on adequate protection against extreme events is addressed. x | |||||
Hájek, Petr; Fiala, Ctislav; Kynclová, Magdaléna | Life cycle assessments of concrete structures - a step towards environmental savings | Structural Concrete | 1/2011 | 13-22 | Articles |
KurzfassungConsidering the volume of concrete produced and the number of concrete structures built, the problem of the associated environmental impact forms a significant part of the entire global problem of sustainable development. Utilization of environmentally optimized concrete structures thus creates a potential for increasing the quality of construction and consequently a reduction of the environmental impact. A life cycle assessment (LCA) is a complex, multi-parametric assessment of the environmental impact of the structure over its whole life cycle. It covers, in one assessment process, all the essential environmental issues, including CO2 emissions, energy consumption, water consumption, waste generation, etc. In the case of concrete, selected criteria should support the design and construction of high-quality and at the same time environmentally friendly concrete structures. The principal problem is to collect relevant environmental input data for specific concrete types plus transport and production processes which can be used in the LCA procedure. x | |||||
Glavind, Mette | Green concrete structures | Structural Concrete | 1/2011 | 23-29 | Articles |
KurzfassungThere are numerous ways of improving concrete structure's environmental performance. An overview of these are presented and exemplified in the present article. They include choice of raw materials, mix design of the concrete, production processes, construction processes, design and use during service life and the end-of-life demolition-crushingreuse. Thus the whole life cycle is considered. This will be the key content of the future fib 3.8 guidelines on green concrete structures which will also include some background information and specific benchmark data. x | |||||
Kawai, Kenji | Application of performance-based environmental design to concrete and concrete structures | Structural Concrete | 1/2011 | 30-35 | Articles |
KurzfassungThe environmental impact and the effect of its reduction must be assessed quantitatively if we are to show clearly the effect of lowering the environmental impact of concrete and concrete structures. One of the quantitative evaluation methods is to regard and verify the environmental impact of concrete and concrete structures as an environmental performance in accordance with the performance-based design method. This article briefly describes the performance-based environmental design method prepared by fib Commission 3 TG3.6 and shows an example of the application of the design method applied to a concrete structure. x | |||||
Noguchi, Takafumi; Kitagaki, Ryoma; Tsujino, Masato | Minimizing environmental impact and maximizing performance in concrete recycling | Structural Concrete | 1/2011 | 36-46 | Articles |
KurzfassungThe sheer amount of concrete in use and in stock compared with other building materials throws up environmental issues such as the huge amount of CO2 emitted when cement and concrete are produced and transported and the enormous amount of waste generated when concrete is disposed of. In addition, we are beginning to deplete aggregate resources at a fast rate. Concrete has conventionally been regarded as being difficult to recycle. The construction industry has addressed these problems and carried out research and development regarding the recycling of concrete since the 1970s. Recycling technology has been shifting from simple crushing into scrubbing with some preparations to produce high-quality recycled aggregate for structural concrete, and recycling of concrete in a completely closed loop has now become technically feasible. This paper reviews the development history of recycling technologies in Japan from the viewpoint of the properties of recycled aggregate and recycled aggregate concrete as well as the environmental impact such as CO2 emissions and waste generation in recycling. The paper also presents the outline of completely recyclable concrete, with which closed-loop circulation of component materials is realized. x | |||||
Ueda, Tamon | International code harmonization: the role of the Asian Concrete Model Code | Structural Concrete | 1/2011 | 47-54 | Articles |
KurzfassungMany national codes in Asia are heavily influenced by those from either Europe or the USA. The climatic, technological and economic conditions together with the material properties in Asia are, however, quite different from those in Europe and the USA, and even different among Asian countries. Thus, many Asian countries need their own national codes with suitable concepts and technologies. At the same time, many construction projects in Asia are carried out in multi-national environments in which various national codes are applied, meaning that international code harmonization is necessary. In order to work for the global issue, such as the construction of a sustainable world, Asia, as the largest economic zone in the 21st century, should take on a leading role. For this purpose, international code harmonization with the new direction of life cycle management (LCM) would provide an efficient way. x | |||||
