دوست کیست ؟

We must learn to understand are another

بايد ياد بگيريم كه يكديگر را بفهميم

اختلاف هميشه پيش مي آيد. در حل اختلاف است كه آدم ها متمايز مي شوند با صحبت و درك نيازهاي ديگري و با اشتياق نشان دادن به حل مخالفت ها هر اختلافي مي تواند و بايد آرام بگيرد مردم بايد با هم اين طور باشند ما بايد با هم اين طور باشيم

مردم وقتي كامل اند كه يك دوست واقعي داشته باشند كه آنها را بفهمد كه در رنج ها و اندوه هاي شان سهيم شود و همه عمر كنارشان بماند

دوست كسي است كه همه كارهاي تو برايش مهم باشد

دوست كسي است كه در خوشي ها و ناخوشي ها به او رو كني

دوست كسي است كه همه كرده هاي تو را بفهمد

دوست كسي است كه حقيقت را درباره خودت به تو بگويد

دوست كسي است كه بداند در هر حال چه بر سر تو مي آيد

دوست كسي است كه با تو رقابت نكند

دوست كسي است كه وقتي همه چيزبراي تو خوب است از ته دل خوشحال شود

دوست كسي است كه وقتي اوضاع خوب نيست بكوشد تو را شاد كند

دوست كسي است كه امتداد تو باشد و بدون او كامل نباشي

Advanced Analysis and Design of Steel Frames

Publisher: Wiley
Language: English
ISBN: 0470030615
Paperback: 384 pages
Data: Jun 2007
Format: PDF
Description: Steel frames are used in many commercial high-rise buildings, as well as industrial structures, such as ore mines and oilrigs. Enabling construction of ever lighter and safer structures, steel frames have become an important topic for engineers.

This book, split into two parts covering advanced analysis and advanced design of steel frames, guides the reader from a broad array of frame elements through to advanced design methods such as deterministic, reliability, and system reliability design approaches. This book connects reliability evaluation of structural systems to advanced analysis of steel frames, and ensures that the steel frame design described is founded on system reliability.

Important features of the this book include:

* fundamental equations governing the elastic and elasto-plastic equilibrium of beam, sheer-beam, column, joint-panel, and brace elements for steel frames;
* analysis of elastic buckling, elasto-plastic capacity and earthquake-excited behaviour of steel frames;
* background knowledge of more precise analysis and safer design of steel frames against gravity and wind, as well as key discussions on seismic analysis.
* theoretical treatments, followed by numerous examples and applications;
* a review of the evolution of structural design approaches, and reliability-based advanced analysis, followed by the methods and procedures for how to establish practical design formula.

Advanced Design and Analysis of Steel Frames provides students, researchers, and engineers with an integrated examination of this core civil and structural engineering topic. The logical treatment of both advanced analysis followed by advanced design makes this an invaluable reference tool, comprising of reviews, methods, procedures, examples, and applications of steel frames in one complete volume.

Filters and Filtration Handbook, Fifth Edition

Publisher: Elsevier Science
Language: English
ISBN: 1856174646
Paperback: 520 pages
Data: Jun 2008
Format: PDF
Description: Filters are used in many industries, especially the water,sewage,oil, gas, food and beverage, and pharmaceutical industries. This new edition of a well-established title retains the aim of being a practical account of filtration equipment and its applications. The previous edition is badly out of date, and Ken Sutherland has completely revised and re-written it, changing emphasis and content wherever necessary. It remains an essential book for the engineer working in a plant situation, who requires guidance and information on what is available and whether it is suitable for the job in hand.

آنالیز آسیب و الاستوپلاستیک ورق ها و پوسته ها (سازه های پوسته ای) Elasto-Plastic and Damage Analysis

 

Elasto-Plastic and Damage Analysis of Plates and Shells

Publisher: Springer
Language: English
ISBN: 354079350X
Paperback: 208 pages
Data: Sep 2008
Format: PDF
Description: This book presents a finite element model for the elasto-plastic and damage analysis of thin and thick shells. Linear elastic, inelastic and softening behaviors caused by damage in structural shells, as well as large rotations are investigated. The textbook is addressed to graduate students and researchers in civil, mechanical and aerospace engineering as well material scientists and applied mechanicians.

The formulation presented here was developed primarily for large scale structural analyses. Special emphasis is therefore placed in computational efficiency. Despite ever increasing capabilities of nowadays computers, small scale constitutive models are hardly ever applicable to analysis of large structures. This book provides a constitutive model which allows for accurate representation of the non-linear shell behavior up to failure, while offering high efficiency and applicability to large scale structural analyses. This is achieved by representing the elasto-plastic behavior by means of the non-layered approach, with an updated Lagrangian method used to describe the geometric non-linearities. For the treatment of material non-linearities an Iliushin’s yield function expressed in terms of stress resultants is adopted, with isotropic and kinematic hardening rules. Damage effects modeled through the evolution of porosity are incorporated into the yield function, giving a generalized and convenient yield surface expressed in terms of the stress resultants.
