Structural Stability of Steel: Concepts and Applications for Structural Engineers

Structural Stability of Steel: Concepts and Applications for Structural Engineers 

Theodore V. Galambos

Preference :

In order to truly understand the behavior and design of metal structures, an engineer needs to have a fundamental understanding of structural stability. More so than structures designed using other construction materials, steel structures are governed to a great extent on stability limit states. All major international design specifications include provisions based on stability theory. The purpose of this book is to provide students and practicing engineers with both the theory governing the stability of steel structures and a practical look at how that theory translates into design methodologies currently implemented in steel design specifications. The topics presented in the text pertain to various aspects of elastic buckling and inelastic instability. An understanding of stability limits is very important in the design of structures: Catastrophic failures can, and tragically have resulted from violating fundamental principles of stability in design. Maintaining stability is particularly important during the erection phase of construction, when the structural skeleton is exposed prior to the installation of the final stabilizing features, such as slabs, walls, and/or cladding.

Principles of Testing Soils, Rocks and Concrete

Principles of Testing Soils, Rocks and Concrete

T.S. NAGARAJ

Preference :

In civil engineering, a wide spectrum of materials, natural as well as processed, are adopted for usage. However, a significant involvement is with soils, rocks, and concrete. While rocks and soils are materials of geological origin, concrete is a processed material using these geological materials as ingredients at different stages. The inherent nature and diversity of geological processes involved in the formation of rocks and soils lead to wide variability in their in-situ state. Hence, the geotechnical engineer usually has to adjust his designs to accommodate the prevailing properties of in-situ soils and/or resort to appropriate ground engineering methods. On the other hand, concrete has become an indispensable construction material that most obligingly conforms to new concepts in design with the possibility of realizing the same through advanced construction technology.

Content :

• Introduction
• Rock and Soil as Engineering Materials
• Concrete as a Construction Material
• Soil, Rock, and Concrete Material Analogies and Implications
• Exploration
• Sampling: Requirements and Techniques

 Solved Example on Design And Detailing Of Counterfort Retaining Wall

When the height of the retaining wall exceeds about 6 m, the thickness of the stem and

heel slab works out to be sufficiently large and the design becomes uneconomical. In

such a case counterforts having trapezoidal section fixed at the base slab are provided

at intervals of 1.5 m to 3 m. The counterforts support the heel slab and the vertical stem.

The design principles for different components of the wall are discussed below.

Engineering Materials 1: An Introduction to Properties, Applications, and Design 

D R H Jones

Preference :

Innovation in engineering often means the clever use of a new material—new to a particular application, but not necessarily (although sometimes) new in the sense of recently developed. Plastic paper clips and ceramic turbine-blades both represent attempts to do better with polymers and ceramics what had previously been done well with metals. And engineering disasters are frequently caused by the misuse of materials. When the plastic teaspoon buckles as you stir your tea, and when a fleet of aircraft is grounded because cracks have appeared in the tailplane, it is because the engineer who designed them used the wrong materials or did not understand the properties of those used. So it is vital that the professional engineer should know how to select materials which best fit the demands of the design—economic and aesthetic demands, as well as demands of strength and durability. The designer must understand the properties of materials, and their limitations.

Content :

• Engineering materials and their properties
• The price and availability of materials
• The elastic moduli
• Bonding between atoms
• Packing of atoms in solids
• The physical basis of Young’s modulus

 Design of Isolated Footing Spreadsheet

The isolated footing is used to support the load on a single column. It is usually either square or rectangular in plan. It represents the simplest, most economical type, and most widely used footing. Whenever possible, square footings are provided so as to lessen the bending moments and shearing forces at their critical sections.

Isolated footings are used in case of light column loads, when columns are not closely spaced, and in case of good homogeneous soil. Under the effect of upward soil pressure, the footing bends in a dish-shaped figure. An isolated footing must, for that reason, be provided by two sets of reinforcement bars situated on top of the other near the bottom of the footing. In the case of property line restrictions, footings may be designed for eccentric loading or combined footing is used as a substitute to the isolated footing.

 Calculate Quantities of Materials for Concrete Excel Sheet

Quantities of materials for the production of the required quantity of concrete of given mix proportions can be calculated by the absolute volume method. This method is based on the principle that the volume of fully compacted concrete is equal to the absolute volume of all the materials of concrete, i.e. cement, sand, coarse aggregates, and water. A Concrete structure may consist of beams, slabs, columns, and foundations, etc. based on the type of structure. The volume of concrete required for concrete structure can be calculated by summing up the volumes of each structural member or each part of members.
