HasenBau: Understanding Building Structures Through Mathematics
HasenBau helps prospective and current architecture students understand the structural concepts and calculations used in South Korea by connecting them to the fundamentals of mathematics.
Start where a past exam solution leaves you stuck. Trace unfamiliar formulas back to their principles, then to the foundational concepts behind them. Identify gaps in your understanding and connect the missing pieces.
■ Who It's For
• Students exploring mathematics and building structures before architecture school
• Architecture students revisiting formulas and their applications
• Learners connecting mathematics, mechanics, materials, and structural design
■ Connect Concepts Through Problems
Follow the concepts behind a solution, from beam deflection to flexural rigidity and curvature, then back to differentiation and functions. Explore definitions, basic solution methods, and diagrams before returning to the problem to connect what you have learned.
■ 55 Chapters, 289 Units, Six Levels
Study topics from middle and high school mathematics through engineering mathematics, undergraduate architecture fundamentals and design, and graduate-level structural topics. Follow the expandable table of contents, open a unit from the principles index, or revisit foundations when a problem reveals a gap.
Topics include structural mechanics, materials engineering, concrete, steel, timber and masonry structures, loads, structural analysis, vibration and seismic design, geotechnical engineering and foundations, and construction and structural assessment.
■ Past Exam Questions
Browse an index of 378 past exam questions by exam session or subject. Filter by topic and learning status, or open a random question from your selected range. Of these, 61 include worked solutions written by HasenBau. Availability is shown separately for original question text and worked solutions.
Solutions explain conditions and assumptions, derivations, symbols and units, and conclusions. Open the principles used at each step to see why an equation holds and when it applies.
■ Interactive Diagrams
Adjust loads, cross-sectional dimensions, material strengths, and vibration conditions to update diagrams and numerical values together. Explore paper-textured diagrams and equations with fractions and subscripts. Calculation assumptions and limits of applicability are also explained.
■ Codes and Revisions
Compare original exam conditions with current codes and standards verified during content review. Completed comparisons explain changes, the reasons behind them, their effects on the answer, and sources. Pending comparisons are marked separately. Code and standard information reflects what was verified on the content review date.
■ 236 Technical Terms
Look up terms such as conjugate beam, curvature, stiffness, and effective stress by name or meaning. Entries explain definitions, what the names mean, structural roles, and common points of confusion. Close the glossary to return to the learning screen you were viewing.
■ Unit Conversion and Study Tracking
Convert units for force, stress, moment, and cross-sectional properties within the app, and review the basis for each conversion. Manually mark questions and units as understood, and organize your learning with bookmarks, notes, handwritten annotations, and audio recordings.
Source references are provided for original exam questions. Worked solutions are educational materials written by HasenBau.
