What is performance based structural design?
Performance-based design is founded on the premise that structural systems must meet specific performance objectives. Specific performance expectations are set for the completed design, and processes are prescribed in minimal terms. Performance-based design offers several advantages over prescriptive design.
What is the basic design philosophy of seismic design of structures?
Ductility is one of the most important factors affecting the building performance. Thus, earthquake-resistant design strives to predetermine the locations where damage takes place and then to provide good detailing at these locations to ensure ductile behaviour of the building.
What is performance based engineering?
Performance-based engineering is the design, evaluation and construction of engineered facilities that meet — as economically as possible — the uncertain future demands of owner-users and nature.
What are the basic principles for seismic design in concrete?
In this paper basic principles for seismic design are summarized. There are three basic requirements to be satisfied; (a) strength, (b) ductility and (c) stiffness.
How do you make buildings ductile for good seismic performance?
Reinforcing steel can carry both tensile and compressive loads. Moreover, steel is a ductile material. This important property of ductility enables steel bars to undergo large elongation before breaking. Concrete is used in buildings along with steel reinforcement bars.
What is performance based analysis?
The objective of performance-based analysis is to produce structures with predictable seismic performance. Capacity: The overall capacity of a structure depends on the strength and deformation capacity of the individual components of the structure.
What is a performance based solution?
Performance Solution means a method of complying with the Performance Requirements other than by satisfying the DTS solution of the BCA. Performance Requirements are requirements set out in the BCA which state the level of performance which a Performance Solution must meet or which a DTS is deemed to meet.
What are the characteristics of seismic performance of the building?
These attributes to good seismic performance include the deadweight margin (a deadweight margin of three or more would permit the tray to stay suspended even after large earthquakes), the flexibility of the tray support to base plate attachment, the flexibility of threaded rods from which certain types of trays are …
