SILO GRAIN COLLAPSED BY ROSTFREI STEELS PRIVATE LIMITED IN INDIA

SILO GRAIN COLLAPSED BY ROSTFREI STEELS PRIVATE LIMITED IN INDIA

One more video found on Youtube on silo grain collapses by Rostfrei Steels Pvt Ltd In India.

In this article, I am going to explain about all things are comes in Video of Rostfrei Steels Pvt Ltd In India.

Introduction

Although statistics are not available, hundreds of industrial and farm silos bins, hoppers experience some degree of failure each year. sometimes the failure is complete and dramatic structure collapse. Other times the failure is not as dramatic or as obvious. For example, the crack may form in a concrete wall, rodents in a sheet shell, either or which might appear harmless to the casual observer. Nevertheless, these are dangerous signals which indicate that corrective measures are probably required. 

All Failure By Rostfrei Steels Private Limited In India

Failure of Design Errors

Silo design requires specialized knowledge. The designer must first establish the materials flow properties, then consider such items as flow channel geometry, flow, and static pressure development, and dynamic effects. Problems such as ratholing and self-induced silo vibration have to be prevented while assuring reliable discharge at the required rate. Non-uniform loads, thermal loads, and the effects of non-standard fabrication details must be considered. 

Above all, the designer of Rostfrei Steels Private Limited must know when to be cautious in the face of incomplete or misleading information, or recommendations that come from handbooks, or from people with the “its always been done this way” syndrome.

Having established the design criteria, a competent design has to follow. Here the designer must have a full appreciation of load combinations, load paths, primary and secondary effects on structural elements, and the relative flexibility of the elements. 

Failed Due to Construction Errors

In the construction phase, there are two ways in which problems can be created. The more common of these is poor workmanship. Faulty construction, such as using the wrong materials or not using adequate reinforcement, and uneven foundation settlement are but two examples of such a problem. The other cause of construction problems is the introduction of badly chosen, or even unauthorized, changes during construction in order to expedite the work or reduce costs.

• Incorrect material

Close inspection of contractors’ work is important in order to ensure that design specifications are being followed. This includes checking for use of correct bolts (size, strength,etc.), correct size and spacing of rebar, specified type and thickness of silo walls, etc.

• Uneven foundation settlement

Foundation design for silos is not appreciably different than for other structures. As a result, the uneven settlement is rare. However, when it does occur, the consequences can be catastrophic since usually, the center of gravity of the mass is well above the ground.

• Design changes during construction

Unauthorized changes during construction can put a silo structure at risk. Seemingly minor details are often important in ensuring a particular type of flow pattern (especially mass flow), or in allowing the structure to resist the applied loads.

FAILURES DUE TO IMPROPER MAINTENANCE

Maintenance of a silo comes in the owner's or user's domain, and must not be neglected. Two types of maintenance work are required. The first is the regular preventative work, such as the periodic inspection and repair of the walls and/or liner used to promote flow, protect the structure, or both. Loss of a liner may be unavoidable with abrasive or corrosive products, yet maintaining a liner in proper working condition is necessary if the silo is to operate as designed.

Causes of Silo Grain Collapsed

• The constructed steeled or cemented structure was not properly watered.
• Between the cement and Internal Basalt (murum) layer, there was a gap developed.
• Due to less thickness.
• Steel sheet usage was less quality was not tested in terms of force.

Consequences of Silo Grain Collapsed

• The constructed steel-structured was weaker and was not able to hold the desired load.
• Due to the air gap developed between steel and basalt layer, It could not bear the load.
• The whole load was concentrated on just one painting.
• Due to this load, the base of steel or cemented structure cracked and the fabricated structure on which the Silo Grain was placed was unbalanced.
• All load of silo tank was concentrated at one point.
• The load increased beyond tolerance and the cement base cracked thus resulting in a collapsed structure.
