Load-bearing walls are generally subject to vertical loads such as floor slabs or roof panels and superwalls, and high-rise buildings may also be subjected to horizontal loads. For load-bearing walls that only consider bearing vertical loads, it can be solved by supporting the floor slabs and adding beams, but the construction is very troublesome and has safety risks.
If the upper load is large, it is also necessary to consider the bearing capacity of the substructure such as columns, foundations, etc., so it cannot be easily dismantled.
As for the wall that bears the horizontal load, don't think about it, high-rise buildings are very different from ordinary multi-storey buildings.
In any case, there is nothing wrong with the idea of demolition, the key is to correctly judge whether it is technically possible to dismantle and how to dismantle safely. And these are things that can only be solved by professional structural designers with some experience. Therefore, it is recommended that you ask an experienced professional structural designer to come to the site for consultation.
It is not recommended that you ask for help online, no matter how clever the experts are, they will not be able to help you if they do not have all the data required for the design.
If your family buys a house is.
In the 20th and 30th floors of the building, the structure is a concrete frame structure, so the two sides of the balcony are not load-bearing walls, but soundproof walls made of aerated concrete masonry. If your family buys a house with less than seven floors, the walls on both sides of the balcony are load-bearing walls. >>>More
If it is a reinforced concrete structure, you can knock down the non-load-bearing walls on both sides, which will not affect the overall structure of the house and will be safer.
Friend, from the situation you described, the cracking of this building is not your family, the downstairs may have been through the ground floor, if it was repaired in 2009, it is a quality problem, you can go to the Construction Bureau, reflect to them, they have the right to give a reasonable solution to the quality of the house, you need to write a report, by the community to seal the signature of each resident to ask them to deal with it as soon as possible, related to the safety of residents.
It depends on what wall is shown in the floor plan, and the load-bearing wall cannot be removed. If you don't have a floor plan, knock it off a little bit and look at it, and the mixed territory wall can't be demolished. >>>More
Thick solid lines should not be moved, because it will affect the structure of the house
