LIMIT STATES OF STEEL DESIGN
For a structural designer, it is most important to ensure that the structures and facilities designed by him are: Fit for their purpose Safe Economical and durable. Thus, safety is most important responsibility of a structural designer. But it is ...
What are Methods of Steel Structure Design?
There are three different methods for design of steel structure, i.e. simple design, continuous design and semi-continuous steel design. Joints in structures have been assumed to behave as either pinned or rigid to render design calculations manageable. In simple design ...
Design of Reinforced Concrete Wall – Concept, Calculations
Reinforced concrete wall is designed as a compression member. Reinforced concrete wall is used in case where beam is not provided and load from the slab is heavy or when the masonry wall thickness is restricted. Reinforced concrete wall is ...
Yield Line Theory For Slab Design – Assumptions, Methods of Analysis
What is Yield Line Theory? The yield line theory of analysis is a factored or ultimate load method of analysis. The yield line theory is conducted based on the bending moment of the structural element at its collapse state. The ...
LOAD & RESISTANCE FACTOR DESIGN (LRFD)
Load and Resistance Factor Design Format Of the many multiple safety factor formats in vogue, perhaps the simplest to understand is the Load and Resistance Factor Design (LRFD) format, which is adopted by the ACI Code [Ref. 3.5, 3.8, 3.9]. ...
PERFORMANCE BASED EARTHQUAKE RESISTANT DESIGN
The performance-based seismic engineering (PBSE) produces structures with predictable seismic performance. This approach is not new. Using this approach / model Turbine, Airplanes & Automobiles are made. In these applications one or more prototype are built and subjected to extensive ...
Maximum Deflections of Reinforced Concrete Beams and Slabs As per ACI 318
Maximum ratios of computed deflection to span L for beams and slabs as per ACI 318: The Building Code.
