A Case Study in Complex concrete construction in Australia:A Hybrid Approach of Hand and Machine

Journal of Civil Engineering and Architecture 2024年第2期18卷 69-79页

作者： Chris Knapp Abedian School of Architecture Bond UniversityGold CoastRobina QLD 4226QueenslandAustralia

This paper describes and provides a critique of the design and implementation of the“scoops”-a set of bespoke multifunctioning architectural free-form elements that are a highlight of the new Soheil Abedian School of Architecture at Bond University,Australia,by the office of Sir Peter Cook and Gavin Robotham,CRAB(Cook Robotham Architecture Bureau,London).The development includes the transfer of analogue design processes into digital 3d modeling,which is then analyzed and rationalized via an exchange with consultants and procurement contractors.The complexity of the concrete works necessitated the use of digital fabrication to make their implementation affordable and within time constraints,with said complexity creating a variety of challenges for many aspects of the entire delivery team.The 3d model played a critical role in communicating intent and accuracy at all stages.The use of site-based craftsmanship combined with computer aided design and fabrication overlapped to realize the project.

Development of high performance and high strength heavy concrete for radiation shielding structures

Heavy concrete currently used for construction contains special materials that are expensive and difficult to work with.This study replaced natural aggregate（stones） in concrete with round steel balls,which are inexpensive and easily obtainable.The diameters of the steel balls were 0.5 and 1 cm,and their density was 7.8 kg/m3.Dense packing mixture methods were used to produce heavy concrete with densities of 3500 and 5000 kg/m3.The various properties of this concrete were tested according to the standards of the American Society for Testing and Materials（ASTM）.The results indicated that the construction slump of the concrete could reach 260-280 mm and its slump flow could reach 610-710 mm.More important,its compressive strength could reach 8848 MPa.These results will significantly alter traditional construction methods that use heavy concrete and enhance innovative ideas for structural design.

SOME REPAIR EXPERIENCES FOR REINFORCED concrete STRUCTURES IN SEAPORT WORKS

引用

China Ocean Engineering 1989年第1期4卷 107-117页

作者： Zhuang, Yinghao Lin, Baoyu Nanjing Hydraulic Research Inst China

Owing to the reinforcement corrosion, freezing action and external mechanical attack, some reinforced concrete structures of seaport works in China have been suffering severe damage. A survey showed that more than 40 reinforcement seaport structures and tide barriers had been damaged so that they had only a service period of 7 - 25 years. Therefore, the repair task is difficult. In the present paper, some principles and methods for repairing the reinforced concrete seaport structures are provided and some related technical requirements and materials as well as their preparation and properties are recommended.
