Civil Engineering (Beams,Columns)
The superstructure of a building consists of elements above the foundation like beams, columns, lintels, roofing and flooring. Beams are horizontal members that carry loads and transfer them to columns or walls. Reinforced concrete beams are designed to resist both bending moments and shear forces from loads. There are different types of beams like simply supported, fixed, cantilever, continuous and overhanging beams which are designed based on how they are supported. Columns are vertical load bearing members that transfer loads from beams and slabs to the foundation. Common column types include long, short and intermediate columns. Lintels are short horizontal members that span small openings like doors and windows and transfer loads to masonry, steel or reinforced concrete

Types of failure
This document discusses different types of material failures including yielding, fracture, elastic deformation, wear, buckling, corrosion, fatigue, caustic embrittlement, and stress concentration. It provides definitions and descriptions of each type of failure. Yielding is defined as the stress at which a material begins to deform plastically. Fracture occurs when a material undergoes plastic deformation, strain hardening, and necking, ultimately resulting in rupture. Elastic deformation is reversible and materials return to their original shape once forces are removed. Wear is the displacement of material from its original position due to contact with another surface.

This chapter introduces fundamental concepts of stability theory that are important for structural engineers to understand. Stability is defined as a structure's ability to resist changing shape under loads through small displacements. Instability occurs when a structure is at the limit between a stable and unstable state, where small load increases cause large displacements. The chapter uses simple spring-bar systems to illustrate buckling behavior and post-buckling strength. It also discusses multi-degree of freedom systems and different types of buckling modes like snap-through. Understanding stability theory allows engineers to properly proportion structures to avoid instability failures.

Analysis of Alternate Load Path Method of Modular Structures
This document summarizes a study that analyzed the structural robustness of modular buildings using the alternate load path method. The study modeled a 5-story modular steel building in ABAQUS software and analyzed it under normal loading conditions and two scenarios where modules were removed. The analyses identified alternate load paths, determined stress distributions and structural responses. The results showed how loads redistributed through intact connections to maintain stability when modules were lost. This provides insight into improving the collapse resistance of modular buildings.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Steel design pre 1
- 1. STEEL DESIGN FAILURE MODE COLUMN OF H SECTION
- 2. INTRODUCTION Columns sometimes known as stanchions are vertical steel members in both single and multi-storey frames. They are principal designed to carry axial loads in compression but will also be subjected to moments due to eccentricities or lateral loads or as a result of being part of a rigid frame.
- 3. WHAT IS FAILURE MODE? Failure mode and effect analysis is a tool that examines potential product or process failures, evaluates risk priorities, and helps determine remedial actions to avoid identified problems. The spreadsheet format allows easy review of the analysis.
- 4. WHEN TO USE IT? Failure mode and effect analysis is primarily a quality planning tool. It is useful in developing features and goals for both products and processes, in identifying critical product/process factors and designing countermeasures to potential problems, in establishing controls to prevent process errors, and in prioritizing process subunits to ensure reliability.
- 5. COLUMN TYPES AND FAILURE MODES i. Long Column ii. Short Column iii. Intermediate Column
- 6. LONG COLUMN • Column that fail by elastic buckling, where occurs at compressive stresses within the elastic ranges, a called LONG COLUMN.
- 7. SHORT COLUMN • A very short and stocky column, will obviously not fail by elastic buckling. It will crush and squash due to general yielding and compressive stresses will be in the inelastic range. This column is called SHORT COLUMN.
- 8. INTERMEDIATE COLUMN • This column will fail by inelastic buckling when a localized yielding occurs. This will be initiated at some point of weakness and crookedness. This type of column is called an INTERMEDIATE COLUMN.
- 9. INTERMEDIATE COLUMN (cont.) • Its failure strength cannot be determine using either the elastic buckling criterion of the long column or the yielding the criterion column.
