👉Foundation Design for Gravity and Embankment Dams

⭕️ The design requirements for rock foundations of gravity and embankment dams involve ensuring stability against sliding and overturning, controlling differential deformation, and managing seepage and erosion.

▶️The specific efforts dedicated to these design tasks may vary based on the dam type and geological conditions of the foundation.

▶️Stability against sliding is a primary concern for both the foundation itself and the interface between the dam and the foundation.

▶️This is particularly important for gravity dams compared to earth-fill dams. Overturning is only relevant for gravity dams, where tensile stresses at the heel and high compressive stresses at the toe can develop due to moments.

⏺Calculating the factor of safety against sliding and overturning involves specific methods.

@etconp

👉The characteristics of the seismic motion in a given site are also linked to the local litho-stratigraphic conditions; for a given earthquake, the site's response may differ.

▶️Depending on the local litho-stratigraphic conditions, the seismic motion can be amplified, more or less strongly, or attenuated.

⏺This why the soil factor from the EN 1998 (Eurocode 8) uses different soil factors to compute the ground earth acceleration to compute the base shear the building might face.

👉ራሱን የሚጠግን ሕያው ኮንክሪት

🌟የኮንስትራክሽን ኢንዱስትሪን የሚያሳድጉ አዳዲስ ቴክኖሎጂዎች እየመጡ ነው፡፡

በዓለማችን ላይ ታዋቂው የሮማዊያን ፓንታዮን ግንባታ ከ2000 ዓመት በፊት ከተገነባበት ጊዜ ጀምሮ እስካሁን ኮንክሪትን ለግንባታ ሂደት በስፋት እየተጠቀምነው እንገኛለን፡፡

ሁሌም ቢሆን አንድ የግንባታ ኮንክሪት ምንም ያህል በጥንቃቄ ቢሠራም በአንዳንድ ሁኔታዎች ሊሰነጣጠቅ ብሎም እነዚህ ስንጥቆች ወደ ፍርስራሽነት ሊቀየሩ ይችላሉ፤ ይህን ችግር ለመቅረፍ ሳይንቲስቶች "ሕያው" ኮንክሪትን መፍጠር ችለዋል፡፡

ሳይንቲስቶቹ ይህን ቴክኖሎጂ ለመፍጠር አሸዋ፣ ጄልና ባሲለስ ሱቲሊስ የተባሀ ባክቴሪያን በመጠቀም ነው "ሕያው" ኮንክሪትን ለመፍጠር ችለናል ብለዋል።

የግንባታ ቁሳቁሱም መዋቅራዊ ሸክምን በብቃት የመሸከም ተግባር አለው ያሉት ሳይንቲስቶቹ ኮንክሪቱ ለአካባቢ ተስማሚ ነው ብለዋል፡፡

የተፈጥሮ አደጋዎች እና ከባባድ የአየር ሁኔታዎች ለምሳሌ እንደ የመሬት መንቀጥቀጥ ወይም ከፍተኛ ንፋስ የመሳሰሉ አደጋዎች በሚከሰቱበት ሰዓት ይህ አዲሱ ኮንክሪት ችግሩን መቋቋም ይችላል።

በተጨማሪም ውኃ አይገባውም ምክንያቱም ስንጥቆች በሚከሰቱበት ወቅት የኮንክሪት ውህድ አካላት ራሳቸውን መጠገን ስለሚችሉ ነው፤ በዚህ በከፍተኛ ደረጃ ተመራጭ ያደርጋቸዋል።

ኮንክሪቱ በሥራ ላይ በሚውሉበት ጊዜ ጉዳት የደረሰበትን ጥቃቅን ስንጥቆችን በኬሚካላዊና ሜካኒካል ባህሪያቸውን ሳያበላሹ ራሳቸውን ወደነበሩበት በመመለስ ህይወቱን እንደሚያራዝመው  ታውቋል።

የኮሎራዶ ቡልደር ዩኒቨርሲቲ ቡድን እንዳሉት ሥራቸው ወደፊት በሚሰሩ ህንጻዎች ሂደት ስራ የሚያቀል እና በህንጻ፣ በወለል ላይ ስንጥቆች በሚፈጠሩበት ጊዜ አደገኛ መርዞችን ከአየር ላይ ወይም ከብርሃን በመሳብ ወደ ነበሩበት ለመመለስ የሚያስችል አቅም አላቸው፡፡

👉Prestressed Concrete

➡️A member where the concrete is prestressed by the longitudinal reinforcing steel (tendons) before being subject to external loading is described as prestressed concrete.

➡️The tendons are of high strength steel (1000 to 2000MPa) and the concrete, a also at high strength (50 to 90MPa).

🏷There are two methods of manufacturing:

1⃣Pretensioning the tendons before casting the concrete.

2⃣Post tensioning the tendons after casting the concrete.

🚧A pretensioned member is manufactured by, first, pretensioning the steel tendons over the length of the casting bed, and anchoring the steel to rigid anchor blocks at either end.

▶️The tendons are generally in the form of straight high tensile steel wires varying in diameter from 2 to 7 mm.

▶️The concrete is then cast around the tendons using shuttering to form the required shape of cross section of the member.

▶️Generally within 3 days, using accelerated curing techniques, the concrete has gained sufficient strength to be able to transfer the prestressing force to the concrete by releasing the anchorages.

▶️The shuttering is then removed and the casting bed can be used again.

🚧Post tensioned member is manufactured by first preparing the shuttering which supports sheaths or ducts.

▶️The ducts contain unstressed tendons in the form of straight or curved cables or bars, which are free to move in the direction of their length but are restrained to prevent movement transversely.

▶️The concrete is then poured into the mould and allowed to gain strength.

▶️There is less urgency in this methods of manufacture and the shuttering is removed after a few days.

▶️Later, when the concrete has matured the steel is stressed by jacking against the ends of the beam and anchored using wedges for cables, or nuts on threaded rods for bars.

▶️The method is suitable for members of different cross section and for members which are cast in place on the construction sites where road access us difficult.

🏷The advantages of prestressed concrete

➡️as compared with ordinary reinforced concrete are:

✅Reduced self weight of members

✅No cracks at service load and consequently better durability

✅Increased shear resistance

🏷The disadvantage of prestressed concrete as compared with ordinary reinforced concrete are:

❎Increased cost of materials and shuttering

❎Greater supervision required to ensure concrete strength and magnitude of prestressed forces.

❎Design calculations are more extensive.
