In Japan, the past few decades revealed the vulnerability of wood-framed residential buildings to strong earthquakes. The Kobe earthquake in 1995 caused tremendous loss of lives resulting from the collapse and damage of such structures that significantly affected economic condition. This disaster motivated many researchers to study the mechanisms of collapse of engineering structures in order to prevent further loss of lives in the future. In this paper, an innovative methodology in simulating the dynamic response of wood-framed buildings, for purposes of seismic performance assessment and retrofitting, is presented. The proposed method, which can simulate inelastic behavior of structures, is capable of showing realistic progressive collapse mechanisms and accurate seismic response of structures. The sequence of analyses and results in the form of computer animations are used to help building owners gain a better understanding of the seismic performance of their buildings before and after the structural reinforcement. Applications to real wood-framed residential buildings were used to show the effectiveness of the methodology in seismic performance assessment as well as retrofit plan development.

THE EFFECTIVENESS OF SEISMIC BUILDING CODE PROVISIONS ON REDUCING THE COLLAPSE RISK OF REINFORCED CONCRETE MOMENT FRAME BUILDINGS
Author: Abbie B. Liel , Curt B. Haselton , and Gregory G. Deierlein | Size: 478 KB | Format:PDF | Quality:Unspecified | Publisher: 4th International Conference on Earthquake Engineering Taipei, Taiwan | Year: October 12-13, 2006
This paper examines the effectiveness of building code provisions in mitigating seismic collapse risk by quantifying the collapse risk of four reinforced concrete framestructures. First, an existing and a
new reinforced concrete moment frame building, designed for seismic conditions in coastal California, are compared to illustrate improvements in building code provisions over time, asmeasured in terms of reduction in collapse risk. This comparison is based on four-story reinforced concrete moment frame structures designed to be representative of a) pre-1970 non-ductile reinforced concrete construction and b) modern, ductile reinforced concrete construction. A second group of four-story reinforced moment frame structures is also considered, including modern code-conforming a) special, b) intermediate, and c) ordinary moment frames. These structures are designed for three different sites and the strength and detailing requirements are consistent with what is permitted for each site’s seismic hazard. From analysis of these structures, the uniformity of safety provided by seismic building code provisions across regions of varying seismicity is evaluated.

As we said you before this year is different year for CivilEA, we want to add new features for CivilEA`s users. we want to extend our activity, specially we want to bold the learning here.
at first we want to open new section with name "eLearning", at this section selected users can post their learnings there and other users can ask problems and solve them.
first lesson are in progress and will be post soon.
if any user can help us to improve this section, please post in private section, and tell us the subjects that he/she can activity on it, we`ll give him ability to post there.
CivilEA hahas new and unique news ....
SOOOOOON...

The management of construction projects is a wide ranging and challenging discipline in an increasingly international industry, facing continual challenges and demands for improvements in safety, in quality and cost control, and in the avoidance of contractual disputes.
Construction Management grew out of a Leonardo da Vinci project to develop a series of Common Learning Outcomes for European Managers in Construction. Financed by the European Union, the project aimed to develop a library of basic materials for developing construction management skills for use in a pan-European context. Focused exclusively on the management of the construction phase of a building project from the contractor’s point of view, Construction Management covers the complete range of topics of which mastery is required by the construction management professional for the effective delivery of new construction projects.
With the continued internationalisation of the construction industry, Construction Management will be required reading for undergraduate and postgraduate students across Europe

Written by a leader on the subject, Introduction to Geotechnical Engineering is first introductory geotechnical engineering textbook to cover both saturated and unsaturated soil mechanics. Destined to become the next leading text in the field, this book presents a new approach to teaching the subject, based on fundamentals of unsaturated soils, and extending the description of applications of soil mechanics to a wide variety of topics.
This groundbreaking work features a number of topics typically left out of undergraduate geotechnical courses

Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundreds of research papers and special issues of journals dedicated to the topic. The explosion of primary literature devoted to GPR technology, theory and applications, has lead to a strong demand for an up-to-date synthesis and overview of this rapidly developing field. Because there are specifics in the utilization of GPR for different applications, a review of the current state of development of the applications along with the fundamental theory is required. This book will provide sufficient detail to allow both practitioners and newcomers to the area of GPR to use it as a handbook and primary research reference. *Review of GPR theory and applications by leaders in the field *Up-to-date information and references *effective handbook and primary research reference for both experienced practitioners and newcomers
