Introduction
The design of structures should satisfy trey innate requirements:
1.Stability: The structure should be stable under the deed of loads.
2.Strength: The structure should resist safely stresses induced by the loads.
3.Serviceability: The structure should perform satisfactorily under table service loads.
Stability, strength and serviceability can only be achieved by following basic design principles. This paper presents different geomorphologic failures, so other engineers can benefit from this knowledge.
Building Collapse
voice of a build in Vijayawada knitd one early cockcrow killing a person. On inspection, it was found that the collapsed part was constructed adjoining to the main building with 25mm expansion joint. The collapsed building was constructed on deuce tugs. Each column has 6-16mm main steel. Load from each column is transferred to a single under reamed pile. Which has 6-10mm bars.
It appears that the collapse is due to terzetto causes:
1.The over lap length of steel rods at the articulation of pile & column is inadequate.
2.Structure is unstable due to total of columns used (two only)
3.Unsymmetrical wall load on the structure.
The collapse of the building could have been prevented by structurally connecting it to main building there by providing stability.
Collapse of a FootBridge
A Footbridge in Vijayawada collapsed one day out front open & fell into the canal below killing two painters. The footbridge has a span of 40m. It consisted of two welded trusses, cross girders & precast RCC slabs. On inspection, it was found that the welding is defective.
Prevention
Following the provisions in IS ordinance for structural steel fabrication would have prevented this failure.
Collapse of a Residential Building
One evening in Vijayawada, a three story residential building (Fig 2.) collapsed a day before occupancy killing watchman & his family.
On inspection, it was found that...If you motive to get a full essay, order it on our website: Orderessay
