A hybrid concrete wall is made up of a traditional reinforced with post-tensioned technology. Recent research has shown that (PT) shear walls have wide range advantages when it comes to resisting lateral forces and moments caused by earthquake loading. To explore the PT behavior subjected seismic load, models were augmented various material models, including KCC, CDP, Winfrith for 2D under push...

The development of the construction world in terms innovation has become one methods supporting success to gain advantages cost and time, which is outer wall can generally categorize into cast-in-situ precast methods. (1) Comparison implementing kumkang materials, concrete facades, curtain facades. method 24% cheaper than method, 87% 52% method. Sorted from cheapest most expensive are facades.&...

In recent years many research on composite beams with innovative shear transmission with composite dowels have been conducted and innovative composite constructions have been built. One of the common types of shear connection is the method of rolled girders encased in a concrete slab. The combination of such method and pcb (precast composite beam) technology is called pcb-W (precast composite b...

large panel precast structures are analyzed based on the connection rigidity. however, the connections undergo nonlinear and inelastic response, when subjected to seismic loads. thus, to study the actual behavior of structure, the connection nonlinearity should be implemented in the joints. in this paper, three conventional connection types are modeled based on the envelope of their cyclic resp...

Precast double walls are frequently used for building applications and consist of a pair precast reinforced concrete shells connected by lattice girder creating an inner cavity. Once placed at its final position this cavity is filled with freshly cast compacted concrete. Aside from benefits such as increased ease in installation, reduced cost shorter construction time also some pitfalls recogni...

This article presents a damage detection method for prestressed reinforced concrete (PRC) elements based on free vibration tests and nonlinear damping identification. Integrated static and dynamic experiments were carried out on three precast PRC beam specimens. The static loading induced different levels of damage to the beams. At each damage level, impulsive loading was applied to the beams a...

Shrinkage can be critical factor for the design of structural members due to the length changes by the timedependent deformation. Given the high fluidity and different mixture proportions of SCC, the shrinkage of such concrete can differ from those of conventional concrete or HPC of normal consistency. Proper estimate of autogenous shrinkage of self-consolidating concrete (SCC) can provide engi...

Building waste is a critical issue in current construction. Innovative design strategies are required to reduce the depletion of valuable materials and resources through providing flexible and versatile structures. This study focuses on the development of an industrial, flexible, and demountable wall panel construction system. The panel system consists of concrete blocks with steel connectors t...
