Response Spectrum Analysis

Response Spectrum Analysis Response spectrum analysis is a method of estimating structural response to small, non-deterministic, transient dynamic events. Examples of such events are earthquakes and tremors. Since the exact time history of the load is not known, time-based analysis is difficult to perform. Peak floor acceleration (PFA) is an important parameter that affects the … Read more

Single Degree of Freedom Systems Analysis (SDOF) – Lecture 3

In this video the Single Degree of Freedom System Analysis (SDOF) is discussed in detail. Single Degree of Freedom System The single-degree-of-freedom system controls the speed through a single, second-order differential equation. Only two variables, position and speed, are required to describe the trajectory of the system. Many structures are ideal as single-degree-of-freedom systems. Understanding … Read more

Experimental Reduction of Local Scour around Bridge Piers

Experimental Reduction of Local Scour is shown in this video. Experimental Reduction of Local Scour Local Scour is a complex phenomenon with a three-dimensional flow, usually developing around piers formed in moving rivers. Local squads could cause partial failure or collapse of bridge piers due to high flood speeds. The cost of large bridges with … Read more

Compacting factor Apparatus Test


Compacting factor test is a more precise and more accurate test for determining the workability of concrete. This is test is widely used in the construction fields and laboratories. The ratio of the weight of partially compacted concrete to the fully compacted concrete is called compacting factor also called a compaction factor. The maximum value … Read more
