Stone masonry ( con’td from the above)

👉 The construction of stones bonded together with mortar is termed as stone masonry

🔸 Different types of stones
used for different purposes

1. Heavy engineering works : Granite, gneiss

2. Buildings situated in industrial towns :- Granite and compact sandstone

3. Pavements, railway ballast, doorsits and steps :- Granite slabs and slate

4. Electrical switch board :- Marble slabs and slate

5. Fire resistance works :- Compact sandstone

6. Carving and ornamental works :- Marble and laterite

7. Face work and architectural purposes :- Marble, granite closer gained sand stone

How tall buildings resist the wind Wind is one of the most important factors that architects and engineers have to consider when designing tall buildings. As buildings become taller, they become exposed to the high impact of wind loads that can cause structures…
How tall buildings resist the wind
👉 tapering
tapering (gradual diminution of a width or thickness) a building as it rises is one method used to break up the uniformity that causes vortex shedding- which is an oscillating flow that takes place as wind moved around the top of tall structures creating low pressure areas in the downwind and pulling the structure with suction forces and causing them to sway back and forth. Tapered forms help tall buildings prevent vortex shedding because of the continuously changing plan dimensions over the building height making them less susceptible to severe across-wind direction vibrations. Kuala Lumpur’s Petronas Towers and The Shard in London(shown above), both use this technique to reduce the effect that high winds have on their structures.

1. STRAIGHT STAIR:
In this stair, all the steps are arranged continuously
along in one direction. One flight may be split into
one or more than one flight by interposing a
landing. This stair can be used where narrow and
long space is available for a staircase such as
entrance, porch etc.
Causes of foundation failure and removal measures



1,Poor Ground Preparation

Cut and fill situations should be properly prepared before the structure is started or it may result in improperly compacted soil beneath the foundation.

2,Transpiration

Vegitation, such as trees, shrubs, or other plants, near a foundation can affect moisture levels. Tree roots can dehydrate the soil beneath a home causing soil shrinkage and settlement of the home. Site clearance ላይ 20cm top layer ላይ ያሉ organic materials በደንም ማስወገድ ምክንያቱም organic property of soil affects engineering of soil

3,Drainage

Improper drainage will lead to excess moisture build-up, which could erode or consolidate soils. Excessive moisture may cause heaving of expansive clay soils. Remedial measure is proper drainage and compaction

4. Poor Building Site Preparation

Cut and fill situations, where the soil is removed from part of the building site and stacked on another, needs proper soil stabilization before a structure is built; otherwise unexpected movements of the soil beneath the foundation may occur.

5,Poor Ground Preparation

Cut and fill situations should be properly prepared before the structure is started or it may result in improperly compacted soil beneath the foundation.

6,Poor Soil Conditions

Poor soil, organics.....etc., may cause expansion or consolidation, which contribute to foundation failures. Using the correct foundation repair system can counteract the above conditions. Steel piers and helical piers are often the solutions for your basement or foundation.

Honeycombs are hollow spaces and cavities left in concrete mass on the surface or inside the mass where concrete could not reach. These look like honey bees nest. Improper vibration and workability of concrete are main causes of honeycombs in concrete.
Honeycombs which are on sides are visible to naked eyes and can be detected easily as soon shuttering is removed. Honeycombs which are inside mass of concrete can only be detected by advanced techniques like ultrasonic testing etc.
main reasons are
Improper vibration during concrete.

Less cover to reinforcement bars

Use of very stiff concrete (this can be avoided by controlling water as per slump test).

Places like junction of beam to beam to column and to one or more beams are the typical spots where honeycombs are observed. This is due to jumbling of reinforcement of beams and column rods at one place; special attention is required at such place during concreting and vibrating.

Presence of more percentage of bigger size of aggregate in concrete also prevents concrete to fill narrow spaces between the reinforcement rods.

📄Cube test is carried out for each 30m usage of concrete.
📄RMC : Ready Mix concrete, The concrete is made at factory and transported to the site, This type of concrete is used where there is a lack of space for mixing the concrete and used where a huge amount of concrete is required for construction.
📄The height of floor is usually 3m or 10ft (If a person asks you whats the height of 12 storied building?
Ans: 3m x 12floors = 36m)
📄A head mason can work 25-30m in a day.
📄In construction, the rate analysis for the work of workers is calculated in Man Hours. (Ex: 10 Birr for 1 Man hour)
📄Cantilever Beam has One fixed support and the other end is free.
📄Simple supported beam has a minimum of two supports.
📄PCC (Plain Cement Concrete) this type of concrete is used on members only when the tensile forces are not acting on it.
📄The weight of first class clay brick should be 3.85 Kg. and it has a crushing
strength of 10.5MN/m
📄Adding more water in the concrete mix to increase setting time leads to form
the Cracks or honeycomb in hardened concrete.
📄Vibration in freshly made concrete is done to remove the air bubbles in concrete mix.
📄Impermeability of concrete: The concrete which resists the the entry of water or moisture into it.
📄The concrete can be lifted to a maximum height of 50m using Concrete
