Description

The rise of terrorism activities has promoted the fast development of new construction materials that can be used to enhance the resistance and resilience of buildings and infrastructures against blast loads. As a notable representative, ultra-high performance concrete (UHPC) has now been widely investigated by government agencies and universities. UHPC inherits many positive aspects of ultra-high strength concrete (UHSC) and is equipped with improved ductility as a result of fibre addition. These features make it an ideal construction material for bridge decks, storage halls, thin-wall shell structures, and other infrastructure against seismic, impact and blast loads. Pioneering applications of this material are now being seen world-wide.

A detailed overview of UHPC development and application is provided first. Succeeding chapters then present case studies on the novel development of the new generation UHPC with nano additives. To get an in-depth knowledge of the blast resistance performance of this novel UHPC material, field blast test results on reinforced concrete columns made with UHPC as well as the UHPC filled double-skin tubes columns are also required and compiled. The residual load-carrying capacities of blast-damaged structural members are also assessed in detail. The exceptional performance of novel UHPC materials illustrates its potential in protective structural design.

Key Features

  • Focuses on principles behind UHPC production, properties, design and detailing aspects
  • Presents a series of case studies and filed blast tests on columns and slabs
  • Focus on applications and future developments

Readership

Civil and structural engineers, materials scientists, architects and structural designers, PhD students working in materials, blast and impact engineering
