  OPTIMIZED LIVE LOADED VIADUCT BRIDGES In the Present state of the art, a Bridge Engineer usually optimize the design component in four ways. This article will discuss about the possibility to optimize the design loads with  Effective Live Load Concept. Problem Statement: Criteria 1: The vehicle volume in the road is majorly classified into two types namely passenger vehicle segment & commercial vehicle segment. Around 90% of vehicles on road are passenger vehicle segment and only 10% of the vehicle is under commercial vehicle segment. Commercial vehicles are higher weight compared to passenger vehicles. But a Bridge Engineer is pulled to compulsion in designing the bridge for the governing vehicle load that is a commercial vehicle, even though their volume is less compared to a passenger vehicle. As per Indian scenario, IRC Class AA & A are far higher than the normal vehicles. Criteria 2: In a densely populated city there will be always an alternative route to reach a destiny

Innovative Idea to reduce the Metro Viaduct Height Usual metro rail viaduct’s deck width will be in the range of 8.8 to 10.5m, which can be easily accommodated within the 1st lane of underneath traffic. If the 1st lane on both side of the underneath traffic is restricted with height constrains for vehicular traffic (say 3.0m), then the vertical profile can be lowered. The vehicle's with height greater than the restricted height can use the other lanes. This will ultimately help in saving the pier quantity w.r.t to concrete & steel. This will also help in reduction of design forces for the substructure and foundations; since the height of pier is reduced. Constraints in implementing the Idea In cities where the alignment has to cross much road intersection, this ideology will not provide sufficient head room clearance. Because in such case the vertical profile need to be lower/rise; but the allowable gradien

 EPISODE 1 - INTRODUCTION ‘Health is wealth’ is a world-famous proverb concerning health. A healthy body is defined as the overall ability of the body to function well. It includes the physical, mental, emotional, and social health of all individuals. A healthy body holds major components that aid the functioning of the body. The first essential component is the state of physical health. Physical health refers to the state of being physically healthy devoid of any illness or diseases. When one maintains good physical fitness, they tend to have an extended lifespan.  The next health component is the mental health or mental well-being. Mental health refers to a state of emotional and psychological well-being of the individual. A person’s mental well-being impacts their emotions and behavior in handling situations. The best-recommended way to maintain mental health is by staying positive and meditating. To perform well and remain active in our  professional life we must stay fit and fine.

 EPISODE 20 SAMRUDDHI EXPRESSWAY VUP COLLAPSED Place  Maharashtra's  Samruddhi Expressway,  (Nagpur-Mumbai Super Communication Expressway) Package -3 Date of Incident: 7/1/2021 Fatality: Officially No Contractor : NCC Reason:  VUP collapsed due to over dumping of green concrete concentrated to a portion over the slab, which leaded to load concentration over a point, as due to which the ground support system failed to carry the load, eventually lead to collapse.

 EPISODE 19 GARUDA VARADHI FLYOVER GROUND SUPPORTING FRAME COLLAPSED Date of Incident: 25/1/2021 Contractor: AFCONS Fatalities  - Officially NO About the Incident: Usually due to some site constraints, some spans will be casted with Ground Support System where LG Launching is not possible,  In the Incident, there was a down Gradient from the pier to pier levels, even they used the standard Ground Support System which is normally used in Segment/Viaduct Construction. Due to improper interlocking with the  end tower with pier might be the reason of the Span Collapse. Video of the Incident All Episodes of Engineering Lessons

 LASER DIFFRACTION SYSTEM Vs HYDROMETER FOR GRAIN SIZE ANALYSIS This Article was aimed to validate the usage of the LDS method as a reliable replacement of the hydrometer method for grain size analysis of fine-grained geo materials. The findings of this study indicated that the LDS method could be a standalone technique for particle size analysis of fine geo materials and can reproduce the hydrometer results with appreciable precision. Using the Microtrac S3500 LDS instrument with samples prepared at a concentration of 1.4 g/l in a distilled water solution, a default refractive index value of 1.75, and without the addition of a dispersing agent or sonication, the results were proven to be satisfactory. Based on the liquid limit of the samples, a mathematical model was provided to select the distribution method (either volume or number) to yield the closest results in comparison to the hydrometer method. Based on the provided equation; any sample with LL >= 180% will result in the nu

  MAHA METRO MACHINARY COLLAPSED Place of the Incident : Maha Metro, Pune Metro Project  Date of the incident: Jan 2019 No Fatal Reports The incident took place as the machine operator could not gauge the sogginess of the soil that caved in. This happened during underground utility checking by the 30 foot piling rig.  which narrowly misses two key flyovers in the area. The site team missed to place the machine on firm ground, which caved during lifting heavy loads. In case of Accidents in working place a fire engine is mandatory to rescue them. But the officials did not ensure the presence of a fire engines. Negligence  is the main reason for the incident. How to avoid this kind of Incidents? There are a range of risks associated with crane operation; Crane pads made of fabricated steel are adopted to distribute the high loading pressure of the crawler crane. The interaction between the crane pad and soil is complicated, and depends on the pad stiffness and the strength and stiffness o
