dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

This paper presents the residual mechanical properties of concrete made with crushed bricks and clay roof tile aggregates after exposure to high temperatures. One referent mixture and eight mixtures with different percentages of replacement of natural aggregate by crushed bricks and roof tiles are experimentally tested. The properties of the concrete were measured before and after exposure to 2...

Previous research has highlighted the efficacy of the application of lean production principles in the precast concrete industry. The work also highlighted the dependence of engineered-to-order prefabrication in construction on both engineering and on process control information for production in construction. In current practice in most precast/prestressed plants in the US, producers typically...

Here we document the behavior at wall scale of a hemp-based hygroscopic material under various temperature and moisture dynamic conditions. The was made precast hemp concrete (HC) blocks with air cavities. It tested within bi-climatic chamber monitored thanks to hygrothermal sensors in chambers. results from an in-house heat transfer model were compared experimental data, using actual thermal h...

To comply with recent international trends and initiatives, and in order to help achieve sustainable development, Korea has established a greenhouse gas (GHG) emission reduction target of 37% (851 million tons) of the business as usual (BAU) rate by 2030. Regarding environmentally-oriented standards such as the IGCC (International Green Construction Code), there are also rising demands for the ...

In this study the fire test was performed to investigate mechanic behaviors and failure patterns of precast normal weight concrete (NWC) lightweight (LWC) walls with three types commonly used steel connectors, namely dry (61), wet (81), bearing (56E) connectors. For LWC wall specimens, on lateral application tension, cracking load values dry, wet, bearing-type connectors were 95.1%, 86.3%, 83.0...
