Enhancing the ease of construction fillers and large-span floors their overall mechanical performance is critical for prefabricated hollow slabs in modular building structures. Therefore, we propose a novel assembly integral two-way floor structure (8.4 × 8.4 m) consisting permanent (BDF ribbed steel mesh box) three precast one-way hollow-core with I-shaped flexural sections to address above pr...

The main challenge in designing Light-Weight Concrete (LWC) is to adapt most of the design, production, and execution rules from normal-weight concrete. Carbon Fiber-Reinforced Polymer (CFRP) composites provide strength stiffness composite system. This study investigated an LWC flat slab with CFRP when subjected human-induced vibration. was determined by finding natural frequency comparing it a...

This research study the reliability of designing continuous floor slabs with varying end conditions under affected ultimate Loads by plastic theory. paper has adopted an approach using moment distribution method in design solid .16 rectangular have same depth but different and dimensions x y- directions were investigated. The results obtained from achieved equilibrium, mechanisms, it was compar...

In order to mitigate climate change, reductions of energy consumption are required on heating systems for residential and non-residential buildings. Despite radiant floor being widely used due their high thermal efficiency comfort, further improvements necessary reduce the carbon footprint mortars used. This paper studies use lime mud, a by-product industry, as partial replacement cement enviro...

Increasing of motorcycle numbers in big cities Indonesia, especially Surabaya. The traffic becomes crowded and road capacity is exceeded. Because the increasing volume, western part Surabaya, government built a flyover west outer ring to provide solution congestion This study aimed determine comparation between PC-I girder PC-U used. In road, method was used calculate prestressed beam fully pre...

The timber structural members of a seven-story building from the end 18th century were evaluated following procedure based on previous research works. structure consisted timber-framed brick walls and heavy floors with mortar filling. Non-destructive measurements taken in 13 sampling areas framed walls. Detailed at least 3 pieces each sample (stress wave Time-of-Flight probing tests). Mean dens...

The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity, which may be increased with addition of traditional fitments such as reinforcing steel, headed studs or shear heads. In addition to these traditional methods of strengthening against punching, steel fibre reinforcement has proved to be an effective and viable alternative. The addition of fi...

Flat slabs are less labour intensive, simplify the installation of services and can accommodate more floors within restricted heights. However, the span influencing their design is the longest and they require more steel compared to two-way slabs. Other drawbacks of flat slabs are vulnerability to punching shear failure and higher deflections. To avoid punching shear failure drop panels, column...

We present a fabrication route for centimeter-scale two-dimensional defect-free photonic crystal slabs with quality factors bigger than 10,000 in the visible, together with a unique way to quantify their quality factors. We fabricate Si(3)N(4) photonic crystal slabs, and perform an angle-resolved reflection measurement. This measurement data is used to retrieve the quality factors of the slabs ...

By applying the technique of polarization bulk-doping in graded AlGaN, it has been possible to create high-mobility three-dimensional electron slabs. Such 3D electron slabs are observed to exhibit clearly resolved Shubnikov de-Haas oscillations. From a temperature-dependent study of the oscillations, we measure the effective mass (m* 1⁄4 0:21m0) and the quantum scattering time (tq 1⁄4 0:3 ps) o...
