  • How to start learning structural engineering and design

    To start learning structural engineering and design, you must build a foundation in mathematics and physics before advancing to specialized structural analysis and material-specific design. Because structural engineering is a regulated profession, formal education is usually required for a career, but self-study is a viable way to gain introductory knowledge. 

    1. Build Foundation (Prerequisites)

    Before tackling structural topics, you must be proficient in the following:

    • Mathematics: Calculus (I, II, and III) and Linear Algebra are essential for understanding force vectors and structural mechanics.
    • Physics: Mastery of Newtonian physics, specifically Statics (the study of forces on non-moving objects), is the bedrock of the field.
    • Core Concepts: Learn about “Load Paths”—how a force (like gravity or wind) travels from a roof, through beams and columns, into the foundation and the ground. 

    2. Learn Structural Theory

    Once you understand the basics, move to the core academic subjects:

    • Mechanics of Materials: Study how materials (like steel and concrete) deform under stress and strain.
    • Structural Analysis: Learn how to calculate internal forces (shear, moment, axial) in trusses, beams, and frames.
    • Introductory Books: Consider reading Structures: Or Why Things Don’t Fall Down by J.E. Gordon for a conceptual introduction, or textbooks like Structural Analysis by R.C. Hibbeler for technical depth. 

    3. Master Software and Drafting

    Modern design is heavily reliant on digital tools: 

    • Drafting (CAD/BIM): Learn AutoCAD for 2D drafting and Revit for 3D Building Information Modeling (BIM).
    • Analysis Software: Gain familiarity with industry-standard analysis tools like SAP2000, STAAD.Pro, or ETABS. 

    4. Enroll in Professional Training 

    If you are pursuing a career, follow these academic and professional milestones:

    • Degree: Earn a Bachelor’s degree in Civil Engineering or Structural Engineering from an accredited institution.
    • Online Courses: Use platforms like Coursera or edX to find specialized certificates in seismic design or concrete fundamentals.
    • Professional Organizations: Join groups like the Institution of Structural Engineers (IStructE) or the American Society of Civil Engineers (ASCE) for networking and technical seminars. 

    5. Obtain Licensure (For Careers) 

    To practice professionally and sign off on designs, you must typically:

    • Pass the Fundamentals of Engineering (FE) exam shortly after graduation.
    • Gain approximately 4 years of supervised work experience.
    • Pass the Professional Engineering (PE) exam (and specifically the SE exam in some regions) to become a licensed Professional Engineer.

  • Different types of Cracks in Concrete

    Different types of Cracks in Concrete.


    1. Plastic Shrinkage Cracks Hairline cracks in fresh concrete surface due to rapid drying.

    2. Settlement Cracks – Diagonal cracks caused by uneven foundation settlement.

    3. Drying Shrinkage Cracks – Random, map-like cracks due to loss of moisture.

    4. Thermal Cracks – Long, straight cracks from temperature changes.

    5. Structural Cracks Wide and deep cracks indicating structural failure.

    6. Crazing Cracks Fine, surface-level hairline cracks (looks like a network).

    7. Corrosion Cracks Rust-colored cracks caused by expansion of corroded rebar (steel inside concrete).

    8. Alkali-Silica Reaction (ASR) Cracks – Map-pattern cracks with white gel due to chemical reaction inside concrete.

    9. Overloading Cracks – Vertical cracks formed due to excessive load or weight.

  • Recent Earthquake in Bangladesh – LIVE or LEAVE?

    Recent Earthquake in Bangladesh — Live or Leave?

    On 21 November 2025, Bangladesh woke up to one of the strongest earthquakes in recent years. For 26 seconds, millions felt the ground shake, buildings sway, and fear rise in their chest. Offices came to a standstill, parents grabbed their children, and everyone asked the same question:

    👉 “Are we safe here?”
    👉 “Should we leave Dhaka?”

    This article breaks down the quake, the science, the emotions, and the realistic decisions ordinary people face today.

    🔶 What Exactly Happened on 21 November 2025?

    A Sudden 5.7 Magnitude Quake

    • Time: 10:38 a.m. BST
    • Magnitude: 5.7
    • Epicenter: Madhabdi, Narsingdi (very close to Dhaka)
    • Depth: ~10 km (shallow = stronger shaking)

    This wasn’t a distant tremor.
    It was a Bangladesh-centered, shallow, high-intensity shake.

    Damage & Casualties Reported

    • 5–10 deaths (varies by source)
    • Over 100–600 injuries
    • Structural damage in Dhaka, Gazipur & Narsingdi
    • Cracks in buildings, broken walls, falling objects
    • Panic evacuation from high-rises

    Aftershocks That Triggered More Panic

    Within hours:

    • A 3.3 magnitude tremor
    • A 4.3 magnitude tremor
    • Several micro-aftershocks

    People stayed outside for hours, afraid of returning to their homes.

    🔶 Bangladesh’s Seismic Reality: A Wake-Up Call

    Many experts are saying it outright:

    “This earthquake may be a warning — not the main event.”

    Bangladesh stands on major active faults, including:

    • Madhupur Fault
    • Dauki Fault
    • Plate boundary near the Himalayas

    BNBC 2020 places Bangladesh in Seismic Zones 2, 3, and 4 — with Dhaka in moderate to high risk.

    The UN recently declared Bangladesh as one of the world’s most vulnerable earthquake zones.

    So the big question becomes…

    ⚠️ Should You LIVE Here… or LEAVE?

    1. This Was NOT a Catastrophic Earthquake

    A magnitude 5.7 will shake buildings but will not level a city.

    It was serious — but survivable.

    2. Preparedness Works (Ask Japan)

    Countries with frequent earthquakes stay safe because:

    • Buildings are designed correctly
    • Codes are enforced
    • People know what to do

    Bangladesh can learn and adapt.

    3. Realistically, People Cannot Just Leave

    You can’t abandon:

    • Jobs
    • Schools
    • Homes
    • Family roots

    Most people will stay.
    So staying safely is the goal — not escaping.

    ❌ Reasons Some Should Consider LEAVING Certain Buildings or Areas

    1. Old Buildings = Real Danger

    If you live in:

    • Old Dhaka
    • Non-engineered buildings
    • Structures older than 25–30 years
    • Buildings without BNBC seismic design

    You are at higher risk.

    2. Unauthorized or Weak High-Rises

    Thousands of buildings were made without:

    • Proper foundation
    • Shear walls
    • Quality concrete
    • Column-beam integrity

    A larger earthquake could be devastating.

    3. Expert Warning of a Potential Larger Quake

    If your area is structurally unsafe, relocating to a safer building (even temporarily) is wise.

    🔶 What YOU Should Do Now (Practical + Life-Saving)

    1. Inspect Your Building

    Ask a structural engineer to check:

    • Cracks
    • Column sizes
    • Beam depths
    • Foundation design
    • BNBC compliance

    2. Create a Family Earthquake Plan

    Agree on:

    • Safe room spots
    • Exit route
    • Emergency contact numbers
    • Meeting point outside

    3. Office & Schools Must Conduct Drills

    No more ignoring it.

    4. The Government Must Enforce BNBC 2020

    No more shortcuts, no more “manage kore dibo.”

    Lives > profit.

    5. Learn Life-Saving Basics

    Teach your family:

    • Drop, Cover, Hold
    • Staying away from elevators
    • Being aware of weak columns

    🔶 Final Answer: Live or Leave?

    Here’s the truth:

    Most people will continue living here.

    And that is fine — if we learn from this.

    Earthquakes can’t be stopped.
    But deaths can.

    The recent quake was not the disaster.
    The disaster will be if we don’t prepare for the next one.
