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

Housing needs are increase up to one million units per year. Indonesia is also one of the countries that is often affected by earthquake so that the people and Indonesian government need to work on making simple, fast and safe houses. One way is use lightweight panel walls. To increase the strength of the panel wall, reinforcement is needed. This study aims to determine the effect of adding plaster and wiremesh to the compressive strength of expanded polystyrene (EPS) sandwich panel walls. This study uses precast specimen expanded polystyrene panel walls size 180 cm × 61 cm. Consists of panel walls without reinforcement, panel walls with plaster and wiremesh space of 1 cm and 2 cm. The results of the average vertical compressive strength of the EPS panel wall obtained at 0,62 MPa, the panel with the addition of plaster and wiremesh with 1 cm space of 0,77 MPa and the highest compressive strength obtained from panel with the addition of plaster and wiremesh with 2 cm space of 0,84 MPa. The results showed that the addition of plaster and wiremesh will increase the compressive strength of expanded polystyrene sandwich panel walls.

Abstract

This paper discusses the structural design phase of a long-span coal shed structure in a 2x50 MW steam power plant. This study aims to share knowledge on how to design a long-span coal shed structure safely based on the design standards. The main structural system of the coal shed roof is a steel arch space-truss with 120 m of span and 31 m of height above supporting 12.5 m height of reinforced concrete columns. The superstructure contains a roof system and reinforced concrete system. The substructure system consists of a tie beam, pile cap, and bore pile. In the numerical model, all structural members were idealized as frame elements, except the pile cap that to be idealized as shell elements. Then, the soil springs were assigned to the bore pile element nodals with a 1 m interval to simulate the soil-structure interaction. The gravity loads due to dead loads, additional dead loads, live loads, rain loads, and lateral loads due to wind action and earthquakes to be considered. Furthermore, the structural analysis was conducted with non-linear geometric to simulate the large displacement effects and tension only element of the wind bracing. In addition, a simplified method to estimate the structural stability under lateral load was conducted. Based on the structural analysis and structural design, the coal shed structure could fulfill the safety criteria in terms of ultimate and serviceability limit based on the design code criteria. Furthermore, the non-linear geometry and stability issue should be considered with an appropriate structural analysis method.

Abstract

Masjid Agung Kraton Surakarta is located in the city of Surakarta, Central Java Province and is a National Cultural Heritage building. The mosque was built during the reign of Pakubuwana II in 1745 AD with a total area of 19,180 m2. The main building of the mosque measures 34.2 meters x 33.5 meters. The mosque is supported by 4 main pillars (Soko Guru) and 12 additional pillars (Soko Rawa) made of wood. Indonesia is located at the confluence of three major world plates that cause the Pacific earthquake line and the Asian earthquake line. This causes the probability of large earthquake waves, and the frequency of occurrence is quite frequent in Indonesia. According to SNI 1726-2019, houses of worship have a risk category 4, where the building must maintain the function of the building structure during an earthquake. One of the regulations for evaluating a building is SNI 1726-2019. In this study, a tenant mortise joint with a maximum moment of 7.2 kNm and a rotation of 0.124 rad was modeled on the main structure of the Surakarta Grand Kraton Mosque with SAP2000 software. The loading combination is based on SNI 1726 2019 with earthquake loads obtained from the rsa cipta karya site. Based on the structural analysis that has been carried out, the results show that the maximum moment that occurs in the connection is 0.5373 kNm which is located at joint 89 elements 161 and obtained a maximum deformation of 6.442 mm.
