Residential Construction Statistics and Facts

Real Estate

The transformation of soil from a strong realm to a liquid nation due to accelerated stress and differential settlement of footings is known as soil liquefaction.

The characteristics to be taken into account in the stage of architectural planning and structural layout of buildings for protection against earthquakes are:

a) Building configuration
b) Foundation
c) Control of gaps in partitions
d) Reinforced concrete bands in masonry residential buildings.
E) Vertical reinforcement.

The protection measures against floods are:

I) Residence on the banks of rivers and slopes on the banks of rivers should be prevented.
ii) Buildings should be constructed 250 meters away from the sea coast/river bank.
iii) Build adequate drainage system in all areas prone to flooding.
(iv) Assemble the entire village or settlement on an elevated platform higher than the high flood grade.
V) Assemble the building with a plinth level higher than the degree of known excessive flooding.

The measures taken to control land degradation in unique regions of our users are:

I) Soil erosion in mountainous areas can be controlled by creating terraces for agriculture.
ii) Plugging of gullies through the construction of observation dams.
iii) Afforestation can manipulate soil erosion on slopes.
iv) In arid regions, safe haven education, flora belts manipulate overgrazing by using animals and developing thorny bushes to stabilize sand dunes.
V) In semi-arid areas, moisture conservation, weed management and correct control of vacant lots.
vi) The control of mining sports are some of the techniques to reduce land degradation.

The number one goal of earthquake-resistant design is to prevent buildings from collapsing during earthquakes, thereby minimizing the chance of loss of life or harm to humans in or around buildings. There are safe capacities, which are considered in the degree of architectural and structural planning to improve their performance during the duration of the earthquake.

The natural factors responsible for landslides are:
a) If the slopes are steep.
B) If excessive intensity of rainfall occurs.
C) If the slopes are stiff.
D) Soil layers formed by gravity.
E) The rock layers are quite eroded.
F) Poor drainage.

The factors responsible for landslides are:
a) Soil erosion induced by deforestation.
B) Mines and quarries.
C) Excavation without engineering.
D) Construction without engineering.
E) Land use pattern.

If houses cannot withstand the forces of excessive winds and storm surge, those houses are considered prone. Generally, cyclone-prone maxima are lightweight wood-framed systems, specifically older homes where the wood has deteriorated and weakened the walls. Houses made from poorly constructed concrete blocks are also vulnerable.
Urban and rural communities on low-lying islands or in unprotected low-lying coastal areas or river floodplains are considered at risk from cyclones.
Man-made elements responsible for causing landslides:
I) Precipitated soil erosion due to deforestation.
ii) Mines and quarries
iii) Excavation without engineering
iv) Non-engineered construction.
V) Land use pattern.

The configuration of an earthquake resistant building are:

a) The building should have an easy rectangular plan.
B) Long walls need to be supported by Reinforced Concrete Columns.

Foundation of an earthquake-resistant building:

a) Assess the liquefaction capacity of the soil to prevent tilt cracking and shape failure.
B) An adequate base design must be provided so that the building can withstand earthquakes.

Homes vulnerable to landslides are those that are located on:
a) Under hills with outcrops of fractured rock.
B) Steep natural slopes, mainly on weak geological materials.
C) Developed slopes where septic tanks, soil absorption structures are used and the landscape is irrigated.
D) Slopes of clearing or embankment associated with production.
E) Areas in or on drain openings including canyons.
F) Presence of landslides nearby.
The houses most prone to flooding are:
a) If biomass materials such as bamboo, leaves and thatch are used to build huts, then they are easily destroyed by floods and washed away.
B) Residential buildings that can be built with earth-based fabric or with stone and brick in powder mortar.
C) Floodplains attract poor urban dwellers because land values ​​are less expensive.
D) The occupation of regions within the floodplains of the rivers, particularly in regions of high population, has increased vulnerability.

The effects on homes due to flooding are:

a) The water under the high-velocity current carries away the houses.
B) Rising waters can cause homes to float from their foundations.
C) Although the houses remain intact on their foundations, floods can cause more intense damage to the substances.
D) The speed of the water can erode the foundation of the residence, which can also cause the house to collapse.
E) Massive floating objects such as bushes, power poles, etc., can additionally impact standing houses and cause considerable damage.
F) Other varieties of damages are wall erosion, cracks and bulge damage in water supply, sanitation and electricity systems.

The protection measures against floods are:

a) You should avoid residing on the banks of rivers and slopes on the banks of rivers.
B) Buildings should be built 250 meters away from the sea coast/river banks.
C) Build adequate drainage systems in all regions prone to flooding.
D) Assemble the entire town or agree on a raised platform above the high degree of flooding.
E) Assemble the building with a plinth level better than the recognized excessive flood level.

The results of cyclones in buildings are:

I) Punching and blowing of corrugated iron roof sheets attached to steel trusses.
(ii) asbestos brittle failure – cement sheets of commercial shed roofs; the failure of those sheets is generally crests and gable ends.
iii) Failure of large commercial buildings with light roofs and long/high walls due to a combination of internal and external pressures.
iv) Failure of roof and wall factors along the gables, especially due to excessive internal pressures.
V) Failures of overturning of composite partitions of various kinds.
vi) Failures of poorly placed or constructed parapets.
vii) Damage to ceiling/lintel projections.
viii) Damage to improperly connected house windows or window frames.
