This innovative door lock system is designed to make it easier control security in certain homes or rooms. can also be used government offices and factories restrict someone from entering a room that just anyone not enter. In this system, the automatic uses an ID-12 type RFID reader, Tag/Transponder, Arduino UNO R3, 5v Buzzer, Drop Bolt Lock, Relay Module, LCD. The reader as receiver, tag/trans...

Strength tests on single lap joints with one adhesive (AV138/HV998) and layer thickness (0.5 mm), three peel stoppers (brass bolt, nylon bolt steel pin), four lengths (12.5 mm, 25 40 mm 100 mm) were conducted to investigate the effects of varying length stiffness peel-stop fasteners. Joint failure stress decreased, but force increased length. Furthermore, joint was higher stopper. The effect br...

The conventional strengthening strategy on the connection between the steel pile cap and reinforced concrete footing requires a series of complicated processes such as the distribution of reinforcing bars, their anchorage into concrete, and the usage of shear keys. This study investigates the structural performance of steel pile caps strengthened with newly proposed perfobond shear connectors s...

This paper investigates the behavior of a new form V-shaped shear connector. The assessment proposed connector’s performance is conducted through an experimental work fourteen push-out tests. results show that developed connector able to transfer higher load than conventional connectors. In addition, its considered as ductile. Geometrical parameters are studied observe their influence on behavi...

This paper presents a series of tests on cold-formed stainless steel bolted connections. The test specimens were fabricated from three different types of stainless steel, including austenitic stainless steel EN1.4301 (AISI 304) and EN1.4571 (AISI 316Ti having small amount of titanium) as well as lean duplex stainless steel EN1.4162 (AISI S32101). The material properties of the three types of st...
