Lester W. Schmerr Jr. ... 432 pages - Language:‎ English - Publisher:‎ CRC Press; (March, 2024).

This text makes use of symbolic algebra and vector-matrix algebra to demonstrate a new approach to learning statics. Symbolic solutions are obtained, together with the types of solutions covered in other texts, so that students can see the advantages of this new approach.

This innovative text is an extension of second-generation vector Statics courses to a new, third-generation matrix-vector Statics course, a course that addresses deformable as well as rigid bodies and employs MATLAB®.

MATLAB® is used as a “calculator” whose built-in functions are used to solve statics problems. This text uses vectors and matrices to solve both statically determinate rigid body problems and statically indeterminate problems for deformable bodies.

The inclusion of statically indeterminate problems is unique to this text. It is made possible by using symbolic algebra and a new, simplified vector-matrix formulation that combines the equations of equilibrium, the homogeneous solutions to those equations, and a description of the flexibilities found in the deformable elements of a structure to solve directly for the unknown forces/moments.

Bentley STAAD Foundation Advanced 2024 v24.00.00.550 [Size: 1.89 GB] ... STAAD Foundation Advanced is a comprehensive structural foundation design and analysis application that includes specialized features for foundations of many types. You can perform isolated, combined, pile cap, and mat foundations, or more complex foundations, including horizontal vessel foundations and tank annular ringwalls. The application also provides lateral analysis of pile/drilled piers and vibrational analysis for machine foundations.

Analyze and Design-International Standards: Design a wide variety of foundations, from simple spread footings to complicated mats and specialized machinery pads, with the extensive support of international standards.

Loads And Load Combinations: Apply wind and seismic loads using built-in load generators. Calculate loading parameters automatically. Combine lateral load cases with gravity and other types of loads using load combination generators.

Machine Vibration And Settlement: Analyze machine block foundations for dynamic loading. Leverage wizard-based input for fast finite element analysis (FEA) solids model creation, various loading, and soil spring options.

Detail and Document - Reinforced Concrete Drawings: STAAD Foundation Advanced generates drawings for plan, elevation, and sectional views with rebar marks. Schedule drawings provide a summary table for design results. General arrangement drawings include all the footings designed in the project, with grid lines and grid marks that help identify interference. Drawings can be exported to DXF or DWG formats.

Generate Structural Design Documentation: Engineers can produce reports – summaries and detailed calculation sheets – for foundation types such as isolated, combined, pile caps, and foundations for plant equipment. For mat foundations, a powerful reporting system publishes the details of key analysis results, stability checks, detailed and summary reports for concrete design operations, bills of materials, general arrangements, and reinforcement detailing drawings available for ACI 318 codes.

Liangbo Hu, Xiaoqiang Gu, Junliang Tao, Annan Zhou ... 514 pages - Language: English - Publisher: Springer; (May, 2018) - ISBN-10: ‎9811301212 - ISBN-13:‎ 978-9811301216.

This book is the second volume of the proceedings of the 4th GeoShanghai International Conference that was held on May 27 - 30, 2018. This conference showcased the recent advances and technology in geotechnical engineering, geoenvironmental engineering and transportation engineering. This volume, entitled “Multi-physics Processes in Soil Mechanics and Advances in Geotechnical Testing”, covers a wide range of topics in soil mechanics, focusing on the behaviours of partially saturated soils, combined effects of multi-physics processes in geological materials and systems, and emerging methods and techniques in geotechnical in-situ testing and monitoring. This book may benefit researchers and scientists from the academic fields of soil and rock mechanics, geotechnical engineering, geoenvironmental engineering, transportation engineering, geology, mining and energy, as well as practical engineers from the industry.

Each of the papers included in this book received at least two positive peer reviews. The editors would like to express their sincerest appreciation to all of the anonymous reviewers all over the world, for their diligent work.

SeismoSoft Suite 2025 [Size: 1.92 GB] ... SeismoBuild is an innovative Finite Element package wholly and exclusively dedicated to seismic assessment and strengthening of reinforced concrete structures that is targeted to the design office. It is the only civil engineering software worldwide that is totally committed to structural assessment and retrofitting. SeismoStruct is an award-winning Finite Element package capable of predicting the large displacement behaviour of space frames under static or dynamic loading, taking into account both geometric nonlinearities and material inelasticity.

SeismoSelect is an easy and efficient way to search, select, scale and download ground motion data from different strong motion databases that are available on-line. Different criteria may be employed as the parameters of interest, with which to carry out the searches. These include a target response spectrum, different ground motion parameters (e.g. PGA, PGV, Arias or Housner Intensity), information regarding the event (e.g. magnitude, faulting style location, date) or the recording site (e.g. Vs30, epicentral distance). SeismoSignal constitutes an easy and efficient way for signal processing of strong-motion data, featuring a user-friendly visual interface and being capable of deriving a number of strong-motion parameters often required by engineer seismologists and earthquake engineers. 

SeismoMatch is an application capable of adjusting earthquake accelerograms to match a specific target response spectrum, using the wavelets algorithm proposed by Abrahamson and Hancock or the algorithm proposed by Al Atik and Abrahamson. After loading some accelerograms and defining the target response spectrum, users need only to define the spectral matching algorithm, adjust the spectral matching period range, set the required tolerance and the spectral matching is executed. SeismoArtif is an application capable of generating artificial earthquake accelerograms matched to a specific target response spectrum using different calculation methods and varied assumptions. It is noted that the use of real accelerograms and spectrum matching techniques, together with records selection tools, tends to be recommended for the derivation of suites of records for use in nonlinear dynamic analysis of structures. However, in those cases where access to real accelerograms is, for whatever reason, challenging or inappropriate, then a tool such as SeismoArtif will be of pertinence and usefulness. 

SeismoSpect constitutes a simple and efficient platform for signal processing that allows to create a personal library of ground motion records and save them all in a single file making it easy to handle and share large numbers of records. FRP Designer provides an efficient solution for designing FRP strengthening of reinforced concrete columns and beams by computing the strength of reinforced concrete members strengthened with FRP laminates.
