Numerical Analysis of Precast Rubberized Lightweight Concrete Wall Panel

Precast concrete wall panels are common prefabricated building components used to replace conventional burnt clay bricks as non-load bearing walls. Recent researches focused on lightweight concrete wall panel due to its low density which would lead to the reduction in total building load. This resea...
