The document provides information on methods of prestressing concrete, including pretensioning and post-tensioning. It discusses:
- Pretensioning involves stressing steel tendons before the concrete is cast around them.
- Post-tensioning involves stressing steel tendons after the concrete has cured using jacks, then grouting the voids.
- Both methods put the concrete in compression and increase its strength and durability compared to conventional reinforced concrete.
The repair and rehabilitation of concrete structures is necessary to extend their lifespan and ensure durability by restoring structural systems to their original positions. Deterioration can be caused by various factors and have effects that endanger safety and utility, requiring distressed structures to be brought back to line, level, and required strength through rehabilitation methods and materials. Tests are available to determine deterioration in structures in need of rehabilitation through case studies of damaged buildings.

This document discusses technical education and underpinning foundations. It begins with definitions of technical education and underpinning. Reasons for underpinning include new construction, structural issues, soil instability, and excavation. Common underpinning methods discussed include conventional pit method, jet grouting, micropiles, needle beams, cantilever needle beams, and underpinning railway bridges. The document emphasizes that underpinning requires expert design and execution to safely renovate structures and protect surrounding buildings.
The pile foundation uses piles to support walls, piers, and other structures. Piles can be placed individually or in clusters. Piles are used when loose soil extends to great depths, and transfer structural loads to harder soils below through end bearing and side friction. Common pile materials include timber, steel, and concrete. Piles can be load bearing, transmitting loads through end bearing and side friction, or non-load bearing, used as retaining walls or sheeting. Pile capacity is assessed through field load tests or theoretical calculations based on soil properties.
Slab is a thin concrete structure used for flooring that can be square, rectangular, or circular. Slabs vary in thickness from 4-6 inches depending on load and are made of cement, coarse aggregate, fine aggregate, and reinforcement bars. There are several types of slabs including one-way slabs which carry load in one direction, two-way slabs which carry load in two directions, joist slabs which have concrete ribs for support, and precast slabs which are constructed off-site and transported. Other slab types include flat plates, flat slabs, waffle slabs, hollow core slabs, and composite slabs which incorporate a steel deck.
Wall ties are used to connect the two independent leaves or layers of a cavity wall together. They are placed at regular intervals to provide strength and prevent buckling of the slender wall sections under load. Special wall ties are also used when insulating materials fill the cavity. Proper installation of wall ties with sufficient embedment into each leaf is important for structural integrity. Tie bars and straps can also be used to connect walls to floor joists.
Prestressed concrete is a structural material that allows for predetermined, engineering stresses to be placed in members to counteract the stresses that occur when they are subject to loading.
Formwork is a temporary mold used to contain poured concrete until it cures and can support itself. It needs to be strong enough to support the weight of wet concrete and withstand pouring and compaction loads. New materials like steel and plastics are now used for formwork in addition to wood. Slipforming allows for continuous vertical pouring of concrete structures like building cores without relying on external support, by using a formwork that rises slowly on its own as concrete is added.
Confined masonry construction consists of masonry walls reinforced with horizontal and vertical reinforced concrete members. Vertical tie columns and horizontal tie beams confine the masonry walls, enhancing their stability, integrity, and resistance to lateral loads from earthquakes. The construction sequence involves first building masonry walls with tie columns cast in place, then constructing tie beams on top along with the slab. This improves the masonry's performance by reducing brittleness compared to conventional masonry or reinforced concrete frame construction.
This document discusses different methods of prestressing concrete, including pretensioning and post-tensioning. Pretensioning involves stressing steel tendons before placing concrete around them, while post-tensioning involves stressing tendons after the concrete has cured using hydraulic jacks. Post-tensioning allows for longer spans, thinner slabs, and more architectural freedom compared to conventional reinforced concrete or pretensioned concrete. Common applications of post-tensioning include parking structures, bridges, and building floors and roofs.
The document discusses building maintenance, common defects, and remedial methods for RCC structures. It describes three main common defects: foundations, walls, and concrete/RCC frames. For foundations, common issues include differential settlement, uplift of shrinkage soil, and dampness. For walls, issues include cracking, dampness penetration, and failure during cyclones. For concrete frames, common problems discussed are seepage/leakage, spalling of concrete, and corrosion of steel reinforcement. The document provides detailed remedial methods for addressing each of these defects.

Reinforced concrete is a composite material consisting of concrete and steel reinforcement. François Coignet built the first iron reinforced concrete structure in 1853. Reinforced concrete uses the strengths of both materials - concrete is strong in compression and steel is strong in tension. It is used widely in construction for buildings, bridges, tunnels and other structures due to its high strength and durability.
Prestressed concrete is concrete that is placed under compression prior to service loads being applied through tensioning of steel tendons. This counteracts tensile stresses from loads to improve the performance of the concrete. Eugene Freyssinet is considered the father of prestressed concrete, developing techniques like high strength steel wires and conical wedges for post-tensioning in the 1930s-1940s. Prestressing can be through pre-tensioning or post-tensioning, depending on if the steel is tensioned before or after the concrete is cast. Popular post-tensioning systems include Freyssinet, Magnel Blaton, Gifford-Udall, and Lee-McCall methods. Prestressed concrete provides

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.
