In this study, fire resistance tests were performed on a conventional slim floor beam and a prestressed composite beam with corrugated webs, which is suitable for a long-span structure with a reduction in story height by utilizing the prestress and accordion effect. In the fire test program, the ISO 834 standard fire curve was adopted. Key test variables were the effect of prestress, shape of c...

Two patients with massive, composite defects of the total lower lip, chin, and anterior mandible underwent double free-flap reconstruction. A fibular osteoseptocutaneous flap was used to reconstruct the mandible and floor of the mouth and a radial forearm fasciocutaneous composite flap, including the palmaris longus tendon, was used for total lower lip and chin reconstruction. Postoperatively, ...

• This work presents a slim-floor configuration which increases its fire protection. new beam is called “Internally Fire Protected Slim-Floor Beam”. The IFP-SFB based on strategy that does not need maintenance. results in up to 30–60 min of additional resistance. composite concrete-steel fully integrated into the floor depth was developed at beginning 1990s. very good behaviour during event bec...

This in vitro study aimed to investigate the effects of glass-ionomer and flowable composite liners on the fracture resistance of Class II amalgam and composite restorations. Group 1 cavities were restored with amalgam and Group 4 cavities with nanofill composite after the application of a dentin-bonding agent. For the remaining groups, light-cured-glass-ionomer liner was used in a gingival flo...

Over the last few decades, there has been growing interest in use of low-carbon materials to reduce environmental impacts construction industry. The advent mass timber panels (MTP), such as cross laminated (CLT), allowed structural engineers specify a material for variety floor design considerations. However, serviceability issues vibration and deflection are limiting longer span timber-only sy...

In this paper, a new composite floor system using cold-formed thin-walled C steel channel embedment and foam concrete slab is developed. This type of features lightweight, high fire-resistant, anti-corrosion features, can be used for multi-story buildings, providing promising alternative the construction market. Two four-point bending tests were carried out to investigate flexural capacity fail...
