A footing when used for two columns or more than two columns is called combined footing. Combined footing is mainly two types:
Rectangular Combined Footing

Design of steel structure as per is 800(2007)ahsanrabbani
It does not offer resistance against rotation and also termed as a hinged or pinned connections.
It transfers only axial or shear forces and it is not designed for moment
It is generally connected by single bolt/rivet and therefore full rotation is allowed

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

3. FootingsFootings
The function of a footing or a foundation is to transmit the
load form the structure to the underlying soil.
The choice of suitable type of footing depends on the depth at
which the bearing strata lies, the soil condition and the type of
superstructure.

4. Types of footingTypes of footing
Following are the different types of footing used for concrete
structure
• Isolated footing
• Combined footings
• Strap footing
• Mat or raft foundation
• Pile foundation
7. Combined footingsCombined footings
• Combined footings are provided to support two or more
column loads. These may be continuous with rectangular
or trapezoidal in plan as shown. Combined footings
become necessary under the following circumstances:
• when the isolated footings overlap.
• when the exterior column is close to the property line with
the result symmetrical isolated footing can not be
provided.
8. Strap footingStrap footing
• Strap footing is one of the types of combined types of
combined. It consists of an isolated footing of two
columns connected by a beam called strap beam. The
strap beam does not remain in contact with the soil and
thus does not transfer any load to the soil. This is
provided when one of the columns is on the property
line.

12. PROBLEMPROBLEM
An isolated footing is to be provided for a column of section
400 mm x 400 mm. The following details re given:
Height of the column =3m
Main reinforcement in column = 4 Nos. 16 mm diameter.
Transverse reinforcement = 6 mm at 220 mm c/c
Plan size of footing = 2.7 m x 2.7 m
Depth of footing at column face = 500 mm
Depth of footing at edge = 150 mm
Depth of foundation = 1000 mm
13. Isolated footingIsolated footing Contd..Contd..
Footing reinforcement = a mesh of 20 mm diameter steel at
250 mm c/c.
Grade of concrete= M20
Grade of steel = Fe415
Draw to a suitable scale the following:
• Plan
• Sectional Elevation
• Prepare bar bending schedule 20 Marks
14. Solution:Solution:
Development length in tension = 47φ = 47 x 16= 752 mm
Depth at junction = 500 mm
Leg length available for column bars = Ldt – 500 = 252 mm <
300 mm.
Provide 300 mm minimum.
Development length of 20 mm bars in footing = 47 x 20 = 940
mm
This is provided by the horizontal projection of bars. Bars
need not be bent at ends in to the depth of footing.
15. Number of bars in footing = 11 Numbers at 200 mm c/c with a
side cover of 100 mm.
Width of footing= 10 x 250 + 100 x 2 =2700 mm
Follow all specification of SP 34 and prepare the drawing
