The National Highways Authority of India (NHAI) has confirmed that the Peenya Elevated Flyover connected National Highway-4, officially known arsenic the Dr. Sri Shivakumara Swamiji Flyover, is structurally harmless and acceptable for vehicular question pursuing the palmy completion of a broad load-bearing trial conducted aft caller cablegram repair works.
The flyover, 1 of Bengaluru’s busiest stretches, has undergone repeated repair and attraction works since 2021, peculiarly involving the replacement and strengthening of cables. During each signifier of repair, the elevated flyover was closed to traffic, resulting successful terrible congestion and bumper-to-bumper postulation connected the roads beneath the flyover, particularly on the Peenya, Jalahalli and Dasarahalli stretches.
To measure the effectiveness of the latest repair works and verify the structure’s safety, NHAI carried retired an extended load trial betwixt May 5 and May 8. The investigating was conducted nether the supervision of a method committee and successful accordance with the guidelines prescribed by the Indian Roads Congress (IRC).
Results recovered to beryllium positive
According to officials, the nonsubjective of the trial was to measure the flyover’s load-carrying capacity, structural integrity, stableness and wide show nether simulated postulation loading conditions. The results were recovered to beryllium positive, confirming that the repaired operation meets each required information standards and is suitable for creaseless postulation movement.
“After large repair and strengthening works, it is indispensable to verify that the operation is safe, unchangeable and susceptible of carrying the intended postulation loads. Following the palmy completion of cablegram repair works connected the linear elevated flyover connected NH-4, NHAI conducted a broad load trial to measure the structural show of the flyover,” an authoritative told The Hindu.
As portion of the investigating programme, heavy loaded trucks were strategically stationed astatine captious locations connected the flyover to simulate maximum postulation loading conditions and make the highest expected structural stresses. Engineers utilized precocious monitoring instruments, including deflection sensors, strain gauges, load cells and information acquisition systems, to continuously grounds the structure’s effect during the test, according to officials.
The NHAI authoritative said, “These highly delicate instruments measured cardinal structural parameters specified arsenic stress, strain, deflection, vibration and wide structural movement. During the static load test, the loaded vehicles remained stationary astatine designated positions portion engineers intimately monitored the flyover’s behaviour nether load.”
Analysed data
The collected information was subsequently analysed and compared with permissible limits specified nether applicable IRC standards. Officials stated that each observed readings remained wrong acceptable limits, confirming that the repaired sections fulfill the required information and show criteria.
The load-testing programme covered 2 repaired spans of the flyover. NHAI has indicated that akin tests volition beryllium conducted connected the remaining repaired spans, including sections measuring 34.5 metres and 37.5 metres successful length, to further verify their structural adequacy and load-carrying capableness earlier completion of the wide strengthening programme.
