Abstract - The expanded count of terrorist attacks for the
most part over the most recent couple of time has
demonstrated that impact of Blast loads on structures is a
genuine issue which we ought to be considered during
configuration procedure of structures in spite of the fact that
these sorts of terrorist strikes areextraordinarycasesmade by
man dynamic loads i.e. Blast loads are really needed to
calculate with great attention just like windandseismicloads.
Also, the investigation of behavior of ferrocement composites
under Blast loading that are utilized as lasting formwork in
conventional reinforced concrete structures is introduced in
this report. Single ferrocement panel specimens are tested
experimentally and analytically under Blast load and also the
load deflection behavior is then studied.
The main aim of this research is to compare the behavior of
the ferrocement concrete Blast loading. In this research the
Ferrocement panel with layered mesh modelled in ANSYS
Workbench.
The panels with different sizing are tested analytically under
blast loading in ANSYS Workbench and compared behavior of
ferrocement panels.
Key Words: Ferrocement, Blast resistant design, blast
waves, explosive effect, finite element method.
1. INTRODUCTION
The main aim of this research is to study the behavior of the
ferrocement concrete under Blast loading and study of Blast
resistance of ferrocement concrete in comparison with
normal concrete. Blasts and types of Blasts have been
explained in brief firstly. Furthermore, the normal parts of
Blast procedure had displayed to explain the impacts of
Blasts on structures. To obtain a superior comprehension of
Blasts and attributes of Blasts will empowerustomakeBlast
safe structure planning and considerablyextra productively.
Fundamental methods for expanding the limit of a structure
to give protection from the dangerous impacts is talked
about both with a planning and designing methodology.
Harm to the peoples, deaths and social frenzy are aspects
that must be limited if the danger of bomber activity can'tbe
ceased. Planning and design of the structures to be
completely bang safe is certifiably not a reasonable and
affordable alternative, present time designing and
engineering learning can improve the new as well as old
edifices to reduce the effects of an Blast.
2. AIM
➢To analyze behavior of ferrocement compositesunder the
blast loading by using Finite Element Method
3. OBJECTIVES
➢ To study the behavior the ferrocementpanelsundergoing
blast loading.
➢ Comparative study of ferrocement panels with varying
thickness against blast loading.

5.2 DEFINITION OF BLAST LOAD
A blast is a quick release of potential energy described by a
splendid flash discharged as a capable of being heard blast.
Some portion of energy is discharged as warm radiation
streak and a section is coupled into the air as air impact and
into the soil ground as ground shocks both as radially
expanding shock waves.
Calculation of Peak Overpressure:
Equivalent of TNT- 100 g
Scaled Distance
Where, R is the distance from the point of interest (m) to the
detonation source and W is the weight (more absolutely:the
mass) of the explosive (Tons).
For 20 cm Standoff Distance, Z= 4.25m
Kinney [10] presents a formulation that [10] is based on
chemical type Blasts. It is described by following equation
and has been used extensively for computer calculation
purposes.
Where Z(m/kg1/3) is the scaled distance,EquationandP0is
the ambient pressure.

7 CONCLUSIONS
 It is observed that total deformation for ferrocement
panel with 18 mm thickness is average 23.98% greater
than deformation in 25 mm thickness ferrocement
panel.
 Equivalent stresses developed in ferrocementpanels25
mm thickness are nearly 46.97 % more than stresses
developed in 18mm thickness ferrocement panel.
 Equivalent Elastic Strain developed in ferrocement
panels 25 mm thickness are nearly 58.63% more than
stresses developed in 18mm thickness ferrocement
panel.
 The proposed methodology can be used for
improvement in design criteria forferrocementorother
concrete composite elements subjected to air Blast
loads.
 For longer Stand-Off distance both panels with 25mm
thickness are more durable and providegoodresistance
to Blast as compared to 18 mm thicknesspanels,sofrom
design point of view 25 mm thick ferrocement panel is
preferred.
 In case of edifices which possess greater threat of
occurrence of Blast, ferrocement panels with more
thickness and a greater number of wire-meshes is
recommended.

Dr. Sachin Mulay, Professor, Department of Structural Engineering, Sandip University, Nashik, India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract - The expanded count of terrorist attacks for the most part over the most recent couple of time has demonstrated that impact of Blast loads on structures is a genuine issue which we ought to be considered during configuration procedure of structures in spite of the fact that these sorts of terrorist strikes areextraordinarycasesmade by man dynamic loads i.e. Blast loads are really needed to calculate with great attention just like windandseismicloads. Also, the investigation of behavior of ferrocement composites under Blast loading that are utilized as lasting formwork in conventional reinforced concrete structures is introduced in this report. Single ferrocement panel specimens are tested experimentally and analytically under Blast load and also the load deflection behavior is then studied. The main aim of this research is to compare the behavior of the ferrocement concrete Blast loading. In this research the Ferrocement panel with layered mesh modelled in ANSYS Workbench. The panels with different sizing are tested analytically under blast loading in ANSYS Workbench and compared behavior of ferrocement panels. Key Words: Ferrocement, Blast resistant design, blast waves, explosive effect, finite element method. 1. INTRODUCTION The main aim of this research is to study the behavior of the ferrocement concrete under Blast loading and study of Blast resistance of ferrocement concrete in comparison with normal concrete. Blasts and types of Blasts have been explained in brief firstly. Furthermore, the normal parts of Blast procedure had displayed to explain the impacts of Blasts on structures. To obtain a superior comprehension of Blasts and attributes of Blasts will empowerustomakeBlast safe structure planning and considerablyextra productively. Fundamental methods for expanding the limit of a structure to give protection from the dangerous impacts is talked about both with a planning and designing methodology. Harm to the peoples, deaths and social frenzy are aspects that must be limited if the danger of bomber activity can'tbe ceased. Planning and design of the structures to be completely bang safe is certifiably not a reasonable and affordable alternative, present time designing and engineering learning can improve the new as well as old edifices to reduce the effects of an Blast. 2. AIM ➢To analyze behavior of ferrocement compositesunder the blast loading by using Finite Element Method 3. OBJECTIVES ➢ To study the behavior the ferrocementpanelsundergoing blast loading. ➢ Comparative study of ferrocement panels with varying thickness against blast loading. 4.

MODELLING IN ANSYS 5.1 MODELLING OF FERROCEMENT PANELS Fig-1(a) Slab Fig-1(b) Mesh 5.2 DEFINITION OF BLAST LOAD A blast is a quick release of potential energy described by a splendid flash discharged as a capable of being heard blast. Some portion of energy is discharged as warm radiation streak and a section is coupled into the air as air impact and into the soil ground as ground shocks both as radially expanding shock waves. Calculation of Peak Overpressure: Equivalent of TNT- 100 g Scaled Distance Where, R is the distance from the point of interest (m) to the detonation source and W is the weight (more absolutely:the mass) of the explosive (Tons). For 20 cm Standoff Distance, Z= 4.25m Kinney [10] presents a formulation that [10] is based on chemical type Blasts. It is described by following equation and has been used extensively for computer calculation purposes. Where Z(m/kg1/3) is the scaled distance,EquationandP0is the ambient pressure. 5.3 ANSYS 5.3.1 ANSYS INC Table 3.
