Study Notes

Structural Elements and Design

Pilaster: A masonry column that protrudes from one or both surfaces of a wall, providing aesthetic and structural benefits.
Pinned Connection: Refers to structural components linked via simple connectors such as bolts or rivets, allowing rotation at the joint without moment transfer.
Plastic Design: An approach to structural design that accounts for connections capable of redistributing loads to other areas in the event of overloads.
Portal Bracing: Involves heavy riveting to connect girders and columns, reinforcing the frame from top to bottom for stability.

Concrete Construction

Precast Concrete: Refers to concrete components that are cast and cured in a location separate from their final installation site, enhancing quality control and construction efficiency.
Precast Concrete Tilt-Slab Wall: Acts as a vertical cantilever during erection, secured by supportive elements until it is self-supporting.

Load and Reaction Concepts

Heat Release Rate (HRR): Designation pertaining to the speed at which a fuel ignites and burns, relevant in fire safety design and analysis.
Repetition of Load: Describes a force that is applied intermittently, affecting the structural behavior over time.
Reaction: The resultant forces arising in structures due to external loads, typically observed at the supports of the structure.
Self-Weight: Another term for dead load, representing the weight of the structure itself without any additional loads.

Structural Features and Types

Queen Post Truss: A type of truss design characterized by two compression members, offering effective load distribution.
Rakers: Diagonal bracing members that provide lateral support, enhancing the overall stability of structures.
Rigid Frame: A construction configuration where beams and columns are rigidly connected, maintaining their angular relationship under load without hinging.
Rising Roof: A deformation seen in wood trusses caused by moisture discrepancies within truss chords, leading to a bending of the structure.
Rubble Masonry Wall: Constructed with inner and outer wythes of coursed masonry, filled with random stone that is prone to instability under lateral forces.

Materials and Mortar

Reinforced Concrete: A composite material in masonry where steel reinforcement bars are integrated to enhance structural performance under tensile forces.
Safety Factor: A critical measure indicating the strength margin of materials just before failure in relation to the working stress considered safe.
Sand-Lime Mortar: An early type of mortar made from sand and lime, which can be removed from surfaces with water, indicating vulnerability in structural integrity.

Specialized Construction Terms

Self-Releasing Floor: A construction type where its girders are installed with minimal stability provisions, facilitating flexibility during heavy-timber constructions.
Serpentine Wall: A wall designed in a curvilinear manner, adding unique architectural elements and aesthetic value.
