Development of Ultra High Performance Concrete against Blasts

Author: Chengqing Wu
Publisher: Woodhead Publishing
ISBN: 9780081024966
Release Date: 2018-03-19
Genre: Architecture

Development of Ultra-High Performance Concrete against Blasts: From Materials to Structures presents a detailed overview of UHPC development and its related applications in an era of rising terrorism around the world. Chapters present case studies on the novel development of the new generation of UHPC with nano additives. Field blast test results on reinforced concrete columns made with UHPC and UHPC filled double-skin tubes columns are also presented and compiled, as is the residual load-carrying capacities of blast-damaged structural members and the exceptional performance of novel UHPC materials that illustrate its potential in protective structural design. 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 fiber addition. These features make it an ideal construction material for bridge decks, storage halls, thin-wall shell structures, and other infrastructure because of its protective properties against seismic, impact and blast loads. Focuses on the principles behind UHPC production, properties, design and detailing aspects Presents a series of case studies and filed blast tests on columns and slabs Focuses on applications and future developments

Finite Element Analysis of Ultra high Performance Concrete

Genre: Concrete beams

"Ultra-high performance concrete (UHPC) is an advanced cementitious composite material which has been developed in recent decades. When compared to more conventional cement-based concrete materials, UHPC tends to exhibit superior properties such as increased durability, strength, and long-term stability. This computational investigation focused on modeling the behaviors of existing UHPC structural components including a prestressed UHPC AASHTO Type II girder and a prestressed UHPC 2nd generation pi-girder. Both a concrete smeared cracking model and a concrete damaged plasticity model were tailored to model UHPC within a commercially available finite element analysis package. The concrete damaged plasticity model using three types of tension stiffening definitions can replicate both linear and nonlinear structural responses of both girders reasonably well. A set of UHPC constitutive properties were developed that facilitate the model replication of the local and global responses observed in the series of physical tests. The finite element analysis modeling techniques developed herein are intended to be applicable to other UHPC structural components"--Technical report documentation page.

Ultra High Performance Concrete A State Of The Art Report for the Bridge Community

Author: U. S. Department of Transportation
Publisher: Lulu.com
ISBN: 1329831519
Release Date: 2016-01-14
Genre: Technology & Engineering

Ultra-high performance concrete (UHPC) is an advanced construction material that affords new opportunities for the future of the highway infrastructure. The Federal Highway Administration has been engaged in research on the optimal uses of UHPC in the highway bridge infrastructure since 2001 through its Bridge of the Future initiative. This report presents the state of the art in UHPC with regard to uses in the highway transportation infrastructure. Compiled from hundreds of references representing research, development, and deployment efforts around the world, this report provides a framework for gaining a deeper understanding of UHPC as well as a platform from which to increase the use of this class of advanced cementitious composite materials. This report will assist stakeholders, including State transportation departments, researchers, and design consultants, to grasp the capabilities of UHPC and thus use the material to address pressing needs in the highway transportation infrastructure.

Modeling of Ultra High Performance Concrete UHPC Under Impact Loading

ISBN: 3839602866
Release Date: 2011
Genre: Aircraft accidents

The protection of important building structures against terrorist attacks is an urgent theme, particularly since the attack on the World Trade Center in New York on the 11 September 2001. For the concept of a safe high-rise building under aircraft impact, UHPC as a building material combines the necessary properties of very high strength, fire resistance and energy dissipation in an ideal way. For the calculation and sizing of structural and protective elements, a scientific basis has been developed and validated in this work through the performance of experiments and the material model derived from them.

Ultra High Performance Concrete

Genre: Technology & Engineering

Advances in the science of concrete materials have led to the development of a new class of cementitious composites, namely ultra-high performance concrete (UHPC). The mechanical and durability properties of UHPC make it an ideal candidate for use in developing new solutions to pressing concerns about highway infrastructure deterioration, repair, and replacement. Since 2000, when UHPC became commercially available in the United States, a series of research projects has demonstrated the capabilities of the material. Three State transportation departments have deployed UHPC components within their infrastructure, and many more are actively considering the use of UHPC. This book documents the research, development, and deployment of UHPC components and includes information about its materials and production, mechanical properties, structural design and structural testing, durability and durability testing, and actual and potential applications. The book concludes with recommendations for the future direction for UHPC applications in the United States.
