Embodiment

[0051] Such as Figure 7 and 8 As shown, the reinforced concrete chimney of a certain factory needs to be demolished. The height is 45m, the bottom diameter is 4.35m, the top diameter is 1.6m, and the wall thickness is 0.48m. The chimney needs to be demolished due to the renovation of the factory area. In order to ensure safety, we adopted a numerical simulation-based mechanical demolition method for tall structures to remove chimneys. First of all, we measured the strength of the reinforced concrete chimney on site, and the tensile strength of the concrete was about 35MPa and the tensile strength was 5MPa. The chimney is structurally sound with no serious weathering. Through data query, the density of the reinforced concrete chimney is 2500Kg / m3, and the elastic modulus E is 35Gpa. The above data are used as the basic data for numerical simulation. Secondly, the gap treatment length simulation design is carried out. Due to the relatively large rigidity of the chimney, in...

Abstract

The invention discloses a high-rise building mechanical demolition method based on numerical simulation. The method comprises the following steps: finding out relevant data of the high-rise building required by modeling, establishing a model of the high-rise building, selecting the position of a simulation notch, selecting the notch length of the high-rise building during toppling, determining a demolition and collapse direction, carrying out notch field positioning, and carrying out notch mechanical processing until the high-rise building topples smoothly. On the basis of the principle, ANSYS/LS-DYNA numerical simulation software is adopted for carrying out toppling simulation on the high-rise building; the optimal notch length is determined through numerical simulation. The high-rise building mechanical demolition method has the advantages that the high-rise building mechanical demolition method is simple in operation, notch treatment is performed by machinery, safe and controllableconstruction requirements are met, toppling demolition of the high-rise building is achieved. The defects of blind construction of mechanical demolition and uncontrollable safety factors are effectively overcome, and the requirements of high-rise building mechanical demolition operation safety, controllability, low cost and high speed are met.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a method for mechanically dismantling towering structures based on numerical simulation. Background technique [0002] With the continuous development of society, the tall structures in the city, such as old chimneys, water towers and cooling towers, are no longer suitable for the needs of urban development, seriously affecting the environment or city appearance. Transformation will exit the stage of history. At present, the demolition methods of towering structures mainly include manual demolition, mechanical demolition and blasting demolition: 1) Manual demolition operators should stand on a stable structure or scaffold to operate, and the demolition time is long and the labor cost is extremely high; 2) Mechanical demolition The demolition speed is fast and the cost is low, but the safety factor is difficult to control, the construction is blind, and ...
