Design Codes: I am interested in hearing if structural engineers in Pakistan are undertaking design to European Eurocodes? Or is it all to the American Codes? The Pakistan Building code is not much use. (If you or your company are a Eurocodes design expert, then refer to my profile for contact details). I work overseas and see (and have used) many Structural Engineers and Consulting Companies in India who are proficient in producing design deliverable (GA drawings, detail drawings, analysis, calculations etc) to Eurocodes. They undertake designs for all European countries from India. Great for the company and the country. You can download guides for these codes free online. I would suggest you study Eurocode 1, Eurocode 2 and Eurocode 3 as a minimum to begin with. This will help guide you to design buildings safely, and give you lots of good background information. Each European Country, including Turkey and other countries like Malaysia, Hong Kong use Eurocodes for design. Great for you professional development. Also, Each country have their own National Annexe (specific parameters to the country) to go with these codes. I suggest in Pakistan you use either refer to Turkish or Malaysian National Annexes. Below are the codes (Eurocodes) I am referring to: Hope the list below is useful reference. Eurocode 1: Actions on Structures BS EN 1991-1-1: Actions on structures. General actions.

I have been a regular user of this forum and have learned a lot of topics and concepts from the discussions led by our seniors. However, it seems that over the past two years, the activity on this forum has decreased due to the creation of WhatsApp groups for structural engineering discussions. While WhatsApp groups provide quick answers, they lack proper documentation. Discussions on WhatsApp quickly vanish in the chat history, whereas this forum maintains a record of valuable discussions. Engineers may ask questions in WhatsApp groups for quick responses, but continuing the discussion on this forum ensures that valuable insights are documented and accessible for current and future reference.

Assalaam o Alliakum everyone, I was wondering if someone could refer me some guide/learning material/book/video tutorials to design building by applying response spectrum analysis in ETABS. I am designing a building with extreme torsional irregularity. Seismic Design Category is D and T<3.5T_s so ELF can't be used. I have to apply some dynamic analysis. I know basics of RSA but I want a step-by-step guide to design structure using RSA in ETABs. Any help would be appreciated.

بسم الله الرحمن الرحيم I provided the book in three formats for easy access in the Google Drive links below The Full Book in a Single File: https://drive.google.com/file/d/1gSew3TaAPpEku3tW9fcC4QJ72PaVXBao/view?usp=sharing Separate Book Chapters Files: https://drive.google.com/drive/folders/1tueeYgieZx8zWMsmp3g1enoqPyna6Bp8?usp=sharing Separate Book Subtopic Files: https://drive.google.com/drive/folders/1ljDq3oRMWCaEz2x-QB5kVNB8GB32d0ke?usp=sharing Here is another link in Internet Archive https://archive.org/details/full-book-concrete-design-dr.-wael-hassan-2023 Preface I have been occupied for long time with the idea of writing a professional textbook on the design of concrete structures that presents this challenging subject in a simplified way, yet technically rigorous, accessible to most civil engineering students, even those not to specialize as structural engineers. I had intended that the book reflects my expertise in structural engineering, specifically concrete design, spanning more than 20 years of professional practice, research, and teaching. With that in mind, I developed over the years sets of lecture notes on reinforced concrete design that I used in various academic roles from teaching assistant to associate professor to teach undergraduate students in higher education institutions in the Middle East and North America This “book” is intended as a humble contribution in the field of structural design of reinforced concrete to make it more approachable, handy, and useful to undergraduate students and practicing structural engineers. It represents my set of lecture notes on concrete design developed over the period of eight years. However, most of the material presented, especially on the analysis and systems, can be useful in concrete design using any building code, with proper modifications according to local codes, since the theoretical basis used is common in many aspects among various codes My intent was to wait until I rewrite these lecture notes, with additional formal discussions, in a formal textbook format and assign a publisher to edit and disseminate that textbook professionally. However, given the substantial size of the material and my current academic and professional commitments, this project can take a few more years to be completed in the presentable way I envisioned. I felt guilty to hold back this knowledge further until formal publication although it can help many students and engineers until then, thus I am presenting these lecture notes as is with my handwriting and manual drawings in this “book,” with the intent of revising, upgrading and publishing it professionally in the future. Please refer to the remark in the Introduction chapter for details about the consistency of this book with the latest version of the Egyptian Code ECP 203-2020. The material in its current format is generally self-contained and it helped thousands of civil engineering students and practicing engineers learn concrete design successfully. I retain my publishing rights of this material for the sole intention of publishing the textbook in a more formal manner in the future; however, I grant the right to any individual to use the book for academic and educational purposes or professional design purposes without my permission. I further grant the right to any individual to post this material as is on the Internet and to distribute as is electronically or in print. The only restriction is to reproduce the material in part or whole in a different format without proper citation to use for commercial purposes without permission. Wael M.

الهندسة الانشائية بالجامعات. أسأل الله أن ينفع به ويجعله خالصا لوجهه. ولا تبخلوا في الدعاء لي ان وجدتم فائدة في هذا الكتاب. الكتاب يشمل جميع موضوعات تصميم الخرسانة المسلحة بطريقة ميسطة بدءا من الأحمال والنظم الانشائية حتي الأساسات وتدعيم المنشات في أكثر من 2000 صفحة. لقد شغلتني منذ فترة طويلة فكرة تـأليف كتاب دراسي احترافي في تصميم المنشآت الخرسانية بطريقة مبسطة، ولكنها محكمة من الناحية الفنية، مما يجعل المادة في متناول معظم طلاب الهندسة المدنية، حتى أولئك الذين لا ينوون التخصص في الهندسة الإنشائية. كنت أنوي أن يعكس الكتاب خبرتي في الهندسة الإنشائية، وتحديدًا تصميم الخرسانة الإنشائية، والتي تمتد لأكثر من 20 عامًا من الممارسة المهنية والبحث والتدريس. ومن هذا المنطلق، قمت على مر السنين بتأليف وتطوير مجموعتين من المحاضرات في تصميم الخرسانة المسلحة، استخدمتهما لتدريس الطلاب في جامعات الشرق الأوسط وأمريكا على مدار تاريخي الأكاديمي منذ درجة مساعد تدريس حتى أستاذ مشارك في الهندسة الإنشائية. يهدف هذا "الكتاب" إلى تقديم مساهمة متواضعة في مجال التصميم الإنشائي للخرسانة المسلحة لجعله أكثر سهولة وتناولا وفائدة للطلاب الجامعيين والمهندسين الإنشائيين. والكتاب يمثل مجموعة محاضراتي في التصميم الخرساني ، والتي طورتها على مدار ثمان سنوات. معظم المادة المقدمة، وخاصة فيما يتعلق بالأنظمة الإنشائية والتحليل، يمكن أن تكون مفيدة في التصميم الخرساني باستخدام أي كود بناء، مع التعديلات المناسبة حسب الكود المحلي، حيث أن الأساس النظري المستخدم مشترك في العديد من الجوانب بين مختلف الأكواد المعتمدة. وقد كنت أنوي الانتظار حتى أعيد كتابة هذه المحاضرات وأحدثها، مع إثرائها بمناقشات ومواد توضيحية إضافية، في نسق كتاب احترافي واختيار ناشر لتحرير ذلك الكتاب ونشره بشكل جذاب. ولكن هذا المشروع، ونظرًا لضخامة حجم المادة والتزاماتي الأكاديمية والمهنية الحالية، قد يستغرق بضع سنوات أخرى حتى يكتمل بالطريقة التي تصورتها. ولذلك فقد شعرت بالذنب لتأخير نشر هذا العلم حتى ييسر الله النشر الرسمي رغم أنه يمكن أن يساعد العديد من الطلاب والمهندسين حتى ذلك الحين، وبالتالي فإنني أقدم هذه المحاضرات كما هي بخط يدي ورسومي التوضيحية اليدوية في هذا "الكتاب"، مع نيتي مراجعتها وتحديثها ونشرها بشكل احترافي في المستقبل إن شاء الله. وقد ساعدت هذه المحاضرات على مدار السنوات آلافا من طلاب الهندسة المدنية والمهندسين الممارسين على تعلم تصميم الخرسانة الإنشائية بنجاح. يرجى العلم بأنني أحتفظ بحقوق نشر هذه المادة لغرض وحيد هو نشر الكتاب بطريقة أكثر رسمية في المستقبل؛ ومع ذلك، فأنا أمنح الحق لأي فرد في استخدام الكتاب للأغراض الأكاديمية والتعليمية أو لأغراض التصميم الاحترافي دون إذني. كما أمنح الحق لأي فرد في نشر هذه المادة كما هي على الإنترنت وتوزيعها كما هي إلكترونيًا أو مطبوعة. لكن القيد الوحيد على الاستخدام هو إعادة إنتاج المادة جزئيًا أو كليًا بتنسيق مختلف دون الاقتباس المناسب لاستخدامها لأغراض تجارية دون إذن. دكتور

Apply to local offices. Islamabad has a lot of forms! Make sure you get sucked into a company that keeps you on u paid internships. Entertain paid jobs only. Apart from that, read code, books and literature. Good Luck. Thanks .

Both practices, with and without stiffness modifiers, are followed to decide about the reinforcement requirement against the design forces. Both approaches will lead to a stable structure as long as mechanics holds. Having said that, the stiffness-modifier approach is more conservative, and is better representation of the actual conditions in most cases; one would expect columns to be less cracked than beams, and consequently will attract larger share of unbalanced moments at beam-column joint as compared to un-cracked scenario.

Its more than that. You have to see what seismic zone your building lies and have to select the appropriate level of ductility and over-strength. I would recommend skimming through ACI Chapter 21. I have also attached some documents pertinent to the discussion that will help you develop a better understanding of aforesaid. Go through read them and if you have any question post in the forums Goodluck!
