  Lateral torsional buckling of slender concrete girders according to Stiglat
Posted by: bizo - 05-14-2014, 11:46 AM - Forum: Request for Civil Engineering Documents - No Replies

Does anyone have or know the literature where I could find the exact procedure for lateral stability proof of concrete beams according to Stiglat? I found some stuff on web but can't find some tables for beta and k1, k2 & k3 coefficients?

Or does anyone know any other calculation method for this problem and literature?

thnx

  The Finite-Difference Modelling of Earthquake Motions: Waves and Ruptures
Posted by: cace-01 - 05-10-2014, 04:49 PM - Forum: Structural Dynamics and Earthquake Engineering - Replies (3)

The Finite-Difference Modelling of Earthquake Motions: Waves and Ruptures

Author: Peter Moczo, Dr Jozef Kristek, Dr Martin Gális | Size: 7 MB | Format: PDF | Quality: Unspecified | Year: 2014 | pages: 394 | ISBN: 9781107028814, 1107028817

[Image: 59870872618349385560.jpeg]


[Image: info.png]

Among all the numerical methods in seismology, the finite-difference (FD) technique provides the best balance of accuracy and computational efficiency. This book offers a comprehensive introduction to FD and its applications to earthquake motion. Using a systematic tutorial approach, the book requires only undergraduate degree-level mathematics and provides a user-friendly explanation of the relevant theory. It explains FD schemes for solving wave equations and elastodynamic equations of motion in heterogeneous media, and provides an introduction to the rheology of viscoelastic and elastoplastic media. It also presents an advanced FD time-domain method for efficient numerical simulations of earthquake ground motion in realistic complex models of local surface sedimentary structures. Accompanied by a suite of online resources to help put the theory into practice, this is a vital resource for professionals and academic researchers using numerical seismological techniques, and graduate students in earthquake seismology, computational and numerical modelling, and applied mathematics.

  Soil Mechanics: A One-Dimensional Introduction
Posted by: cace-01 - 05-10-2014, 04:42 PM - Forum: Soil Investigation and Mechanics - Replies (1)

Soil Mechanics: A One-Dimensional Introduction

Author: David Muir Wood | Size: 3 MB | Format: PDF | Quality: Unspecified | Publisher: Cambridge | Year: 2009 | pages: 252 | ISBN: 0521517737, 0521741327, 9780521517737

[Image: 85400042247514616096.jpeg]


[Image: info.png]

This 2009 book teaches the principles of soil mechanics to undergraduates, along with other properties of engineering materials, to which the students are exposed simultaneously. Using the critical state method of soil mechanics to study the mechanical behavior of soils requires the student to consider density alongside effective stresses, permitting the unification of deformation and strength characteristics. This unification aids the understanding of soil mechanics. This book explores a one-dimensional theme for the presentation of many of the key concepts of soil mechanics - density, stress, stiffness, strength, and fluid flow - and includes a chapter on the analysis of one-dimensional consolidation, which fits nicely with the theme of the book. It also presents some theoretical analyses of soil-structure interaction, which can be analyzed using essentially one-dimensional governing equations. Examples are given at the end of most chapters, and suggestions for laboratory exercises or demonstrations are given.

  Performance of buildings during the 2001 Bhuj earthquake
Posted by: TAFATNEB - 05-10-2014, 10:32 AM - Forum: Journals, Papers and Presentations - No Replies

Performance of buildings during the 2001 Bhuj earthquake

Author: Jag Mohan Humar, David Lau, and Jean-Robert Pierre | Size: 4 MB | Format: PDF | Quality: Unspecified | Publisher: Can. J. Civ. Eng. 28: 979–991 (2001) | Year: 2001 | pages: 13

[Image: 60717006044707507433.jpg]


[Image: info.png]

Abstract: The performance of buildings during the January 26, 2001, earthquake in the Kachchh region of the province
of Gujarat in India is discussed. A majority of the buildings in the earthquake region were either of load-bearing masonry
or reinforced concrete framed structure. Most of the masonry buildings were built with random or coursed stone
walls without any reinforcement and heavy clay tile roofing supported on wooden logs. A large number of such buildings
collapsed leading to widespread destruction and loss of life. Many reinforced concrete frame buildings had infill
masonry walls except in the first storey, which was reserved for parking. As would be expected, the open first storey
suffered severe damage or collapsed. Observations of failures confirmed the vulnerability of some structural details that
are known to lead to distress. However, an important observation to come out of the earthquake was that masonry
infills, even when not tied to the surrounding frame, could save the building from collapse, provided such infills are
uniformly distributed throughout the height so that abrupt changes in stiffness and strength did not occur.
