Vibration Analysis of Machine Foundations

Machine Foundation is subjected to dynamic loads. These loads develop the vibratory motions which will transmit into the soil below the foundation. The effect on soil caused by these vibrations is analyzed using principles of soil dynamics and theory of ...

Qualitative Structural Analysis of Beams and Frames

Qualitative structural analysis might not be familiar to structural engineers. The usual way of analysis of structures is numerical (quantitative) method in which the structural designers should determine values for dimensions and loads and compute bending moments and reactions. However, there ...

PORTAL METHOD OF APPROXIMATE ANALYSIS

PORTAL METHOD OF APPROXIMATE ANALYSIS The portal method is an approximate analysis used for analysing building frames subjected to lateral loading such as the one shown in figure 1(a). This method is more appropriate for low rise (say height is less ...

INFLUENCE LINE METHOD OF ANALYSIS

An influence line for any given point or section of structure is a curve whose ordinates represent to scale the variation of a function such as shear force, bending moment, deflection etc at a point or section, as the unit ...

PUNCHING SHEAR

What is punching shear? The failure mechanism of structural elements like slabs and foundation etc. by shear, is called punching shear. Consider a portion of slab subjected to an increasing concentrated load. Eventually the slab will fail. One possible method of ...
