✅ስለ ብሎኬት
. @engineer03
⏩Hollow Concret Block (HCB) ወይም የግድግዳ ብሎኬት/Wall HCB/ በመባል ይታወቃል።
💢የብሎኬት ምርት ሲደረግ ጠቀሜታው ለሁለት ጉዳይ ነው
1. ሸክም መቌቌም የሚችል/Load Bearing/
2. ሸክም መቌቌም የማይችል /Non-Load Bearing/
💢ይሄንን መሰረት ያደረገም የደረጃ ክፍፍል/Class/ ይኖራቸዋል።
💢ሸክም መቌቌም የሚችሉት ብሎኬቶች "ክላስ ኤ እና ቢ" /
Class A and B/ በመባል ሲመደቡ ሸክም መቌቌም
የማይችሉት የብሎኬቶች ደግሞ "ክላስ ሲ" /Class C/ በመባል
ይመደባሉ።
➡ብሎኬት በተለምዶ በመጠናቸው ባለ10፣ ባለ15 እና ባለ 20 በመባል ይለያሉ::

ርዝመት x ስፋት x ቁመት/ Length x width x depth/
ማለትም Standard Dimenssion
⭕️40x20x20cm
⭕️40x20x15cm
⭕️40x20x10cm

👉Note:
1 kilogram per square centimetre = 0.0981 mega pascal

👉Bearing Capacity
.
▶ለ ዛሬ Part One እናቀርብላችኋለን 👇
.
♧ Bearing capacity is the capacity of soil to
support the loads applied to the ground.
♧ The bearing capacity of soil is the maximum
average contact pressure between the foundation
and the soil which should not produce shear failure
in the soil.
♧ Ultimate bearing capacity is the theoretical
maximum pressure which can be supported without
failure;
♧ Allowable bearing capacity is the ultimate
bearing capacity divided by a factor of safety .
♧ There are three modes of failure that limit
bearing capacity:
□ General shear failure,
□ Local shear failure
□ Punching shear failure.
.

.
▶Modes of failure (Part two)
.
1. GENERAL SHEAR FAILURE
*General shear failure involves total rupture of the underlying soil. There is a continuous shear failure of the soil from below the footing to the ground surface.
*The value of Quilt divided by the width B and length L of the footing is considered to be the ultimate bearing capacity (qult) of the footing.
A general shear failure occurs for soils that are
in a dense or hard state.
.
2. LOCAL SHEAR FAILURE
Local shear failure involves rupture of the soil
only immediately below the footing.
*There is soil bulging on both sides of the footing, but the bulging is not as significant as in general shear.
*Local shear failure can be considered as a transitional phase between general shear and punching shear
* A local shear failure occurs for soils that are in
a medium dense or firm state.
.
3. PUNCHING SHEAR FAILURE
*Punching shear, the soil outside the loaded area
remains relatively uninvolved and there is minimal movement of soil on both sides of the footing.
*The process of deformation of the footing
involves compression of soil directly below the
footing as well as the vertical shearing of soil
around the footing perimeter.
*A punching shear failure occurs for soils that
are in a loose or soft state.

✅Recent Building Technologies
✔️Drones✔️
An unmanned aerial vehicle (UAV) or commonly known as Drones have been a major innovation in the last few years offering great benefits to many industries. While they originated mostly in military applications, their use is rapidly expanding to commercial, scientific, recreational, agricultural, and including the construction industry. In just a few years, these drones have almost transformed the construction industry and now play a significant role in the planning, surveying, and data capturing process. they can capture video, take high-resolution images by an operator on the ground. While the uses of drones do not include the actual labour phase of construction (yet), they play a huge role in mapping a construction site, making site inspections and building surveillance in a simplified, budget-friendly and faster way. As more advances are made in drone technology, we believe it will offer more benefits.
