Abstract Light Weight Concrete (LWC) is popularly used in multi-story building frames, curtain walls, shell roofs, folded plates, prestressed or precast elements due to its lower dead load as compared conventional concrete. Although it less popular practice because of high-water absorption capacity, high cost, lack standard specifications, and difficulty consistent batches. This paper presents ...

Abstract Light-weight materials are commonly used in high-rise buildings to reduce the building weight, but their thermal inertia will increase fluctuation of air-conditioning and heating load indoor comfort. Phase-Change Material (PCM) is employed improve behavior by latent storage, its location has obvious impact on improvement light-weight wall. According this condition, taking common multi-...

composite steel concrete composite floor used mainly in the commercial and office building has lighter weight and is considered very economical. the light weight natures of this type of floor causes some vibration problems when it is subjected to loadings such as human footstep loading. the dynamic characteristics of these floors are dependent on several parameters such as joist span, girder sp...
