Abstract

Started from an innovative construction system programmed by the government to provide residential homes in 2007 that is the use of expanded polystyrene concrete as a wall construction. This type of construction provides advantages that can reduce the risk of damage in the earthquakes because it has a relatively light weight which is one of the requirements for earthquake resistant houses. For this reason, the bearing capacity of the wall panel is increased to become an earthquake resistant wall using reinforcement layers. Variations on this research are expanded polystyrene concrete panels without reinforcement, with reinforcement, and with reinforcement and bolt shear connectors. Strengthening uses a reinforcement of Calcium Silicate are Kalsi board. Testing based on SNI 03-3122-1992 (Fibrous Lightweight Concrete Panel). The results showed that the average value of the panel densities was 612,57 kg/m3, the elastic modulus was 942,37 MPa, compressive strength of 2,52 MPa and water absorption capacity of 12,11%. The highest flexural strength was obtained by the panel with kalsiboard reinforcement of 1,60 MPa. This results the addition of reinforcement layers will affect the increase in strength.

Abstract

Many aspects must be considered in the building's design so that the construction is sturdy and can be used according to its function. An important aspect that is often overlooked is the aspect of fire safety. This study aims to evaluate environmental conditions and safety facilities in buildings against fire hazards. The buildings reviewed are the Postgraduate Building, E6, E7, and F3 of the Muhammadiyah University of Yogyakarta. The research method used in this research is a qualitative approach, and the primary data is obtained by direct observation in the field and interviews with the person in charge of the building. This study indicates that the environmental conditions of the postgraduate building, E6, E7, and F3, are not in good condition because each building gets a condition value of 51.67%; 50.56%; 52.22%; and 50%. The rescue facilities in the postgraduate building, E6, and E7 are good; although there are some shortcomings, the value of the condition of each building is 85.98%, 87.41%, and 87.41%. The rescue facility in the F3 building is quite good, with a condition value of 65.81%.
