This presentation discusses the role of different shear connectors in composite steel deck structures from a bond-slip point of view using numerical analysis. It introduces shear connectors and their use in composite construction. It then reviews literature on standard push-off tests, design equations for calculating shear stud capacities, and a study comparing embossed steel plate connectors to headed studs. The presentation outlines the contents as introduction, literature review, finite element modeling, parametric study, results and discussion, and conclusion.

Shear connector in composite construction

4. INTRODUCTION
Advantages of composite slab
• Steel deck act as instantaneous platform to sustain
construction load
• Steel deck provides form work facility for the in-situ
cast concrete
• Function of steel deck as tensile reinforcement
• Reduced construction time

5. INTRODUCTION

• Renovation of existing buildings

6. INTRODUCTION
The need for shear connection

7. LITERATURE REVIEW
General Background
• Importance of shear connection
• Invention of the headed stud shear connector

8. LITERATURE REVIEW
Standard push-off test specimen as per Eurocode4

9. LITERATURE REVIEW
Design equation for the calculation of shear stud
capacities
• PRD= (0.29α𝑑2
(fck*Ec)1/2
)/ϒv ………………(1)
• PRD= (0.8fu*𝜋𝑑2)/ 4ϒv ………………(2)
• Where:
• α=0.2(h/d+1) <1.0
• h is the overall height of the stud
• fck is the characteristic cylinder compressive strength (N/𝑚𝑚2)
• fu is the ultimate tensile strength of headed stud materials ≤500
N/𝑚𝑚2
• ϒv is the partial factor

10. LITERATURE REVIEW
R. Vijaykumar et al [2020]
• Study on Embossed Steel Plate connector

11. LITERATURE REVIEW
• Embossed Steel Plate connector of tear drop pattern
Specimen details
• ESP connector with M30 grade concrete having depth
of 8,10 & 12mm
• Stud connector with M30 grade concrete having
diameter 16,19 & 22mm

12. LITERATURE REVIEW
Conclusion
• ESP connector has high resisting capacity
• ESP (600kN, 650kN and 690kN)
• Stud (330kN, 370kN and 420kN)
• ESP has high stiffness
• ESP-less affected by cracking
