San Marco Bell Tower: Foundation Reconstruction of the Tallest Structure in Venice

Ravi Panwar — Sat, 10 Apr 2021 17:16:04 +0000

San Marco Bell Tower, the tallest structure in Venice, was first constructed around 800 years ago. Located in Piazza Public Square, the tower is among the most distinct symbols of the city. Venetians call the tower “il paron di casa” (the landlord, the master of the house) as it was constructed to guard the dock […]

How to Replace Damaged Concrete Members in Structures?

Madeh Izat Hamakareem — Fri, 27 Mar 2020 14:51:54 +0000

The replacement of damaged concrete elements requires demolition and removal of existing structural elements and their substitution with new members. The demolition process is carried out after proper jacking is applied to relieve imposed loads on the damaged structural member. Great care should be practised to avoid damaging existing steel bars if present. This measure […]

How to Strengthen Existing Concrete Walls?

Neenu S K — Fri, 03 May 2019 08:07:02 +0000

Strengthening of existing reinforced concrete walls becomes necessary either when they lose their strength and capacity to take up the stipulated loads or when you need to increase their load carrying capacity. This kind of rehabilitation is mostly required for walls constructed in high seismic zone areas. Different retrofitting techniques can be applied by using […]

Methods of Strengthening of Foundations in Buildings

Gopal Mishra — Sat, 29 Nov 2014 12:15:24 +0000

Strengthening of columns foundations is required in the case of applying additional loads. Widening and strengthening of existing foundations may be carried out by constructing a concrete jacket to the existing footings. The new jacket should be properly anchored to the existing footing and column neck in order to guarantee proper transfer of loads. This […]

Methods of Strengthening Concrete Columns

Madeh Izat Hamakareem — Fri, 03 Oct 2014 15:35:21 +0000

Column strengthening is a process used to add or restore ultimate load capacity of reinforced concrete columns. It is used for seismic retrofitting, supporting additional live load or dead load that not included in the original design, to relieve stresses generated by design or construction errors, or to restore original load capacity to damaged structural […]

STRENGTHENING OF RINFORCED CONCRETE BEAMS

Gopal Mishra — Tue, 02 Sep 2014 16:15:01 +0000

Reinforced concrete beams need strengthening when the existing steel bars in the beam are unsafe or insufficient, or when the loads applied to the beam are increased. In such cases, there are different solutions that could be followed: I-ADDING REINFORCEMENT STEEL BARS TO THE MAIN STEEL WITHOUT INCREASING THE BEAM’S CROSS SECTIONAL AREA This solution […]
