On the use of 5% EPS concrete compressive strength characteristics obtained amounted to 18.69 MPa (down approximately 20.9% of the normal mixture). While the use of 10% EPS, decrease concrete compressive strength of 21.67% ie 18.51 MPa. Modulus of elasticity of concrete decrease with the addition of the percentage of EPS, the use of EPS up to 40% decrease modulus of elasticity to be 16.219 MPa (down around 21%). The relationship between the modulus of elasticity (E), Specific Gravity (wc), compressive strength (f / c) and the percentage of EPS (p) can be expressed in an empirical equation as follows : E = (wc)1,5·0,05·exp(−0,23·p)·√f / c.

This code covers analysis method and basic assumptions that can be taken by a structural designer to design a reinforced concrete structure. An engineer has to design a flexural component, one of the structural component. One of the flexural component is beam element. SNI 03-2847-2002 adopt capacity design menthod in beam element design. This paper will be discuss a simple design procedure in beam element, based on variabel, which is ratio between /b, with b is the balanced reinforcement ratio. The value is limited to 0,75 maximum in SNI 03-2847-2002. A dactail failure is guarantee in a beam element with under 0,75. The analysis that have been done before, produce the correlation between Mn/bd2 and which can be a tool for design a beam element. A simple calculation use the table (Mn/bd2 vs ) will be present at the end of this paper.

EPS with 5 cm of thickness and 1 m of width used as specimens at this research. The specimens reinforced with wire mesh (4 – 150 mm) both sides, and finished by mortar cement with 1,5 and 3 cm of thickness. Each specimen was tested in the laboratory to obtain their flexural capacity and bearing capacity. Specimen with 8,5 cm of thickness has 150 kg/m2 of flexural capacity, while specimen with 11 cm of thickness has 450 kg/m2 of flexural capacity. Alternative wall panel with EPS, can be used as a bearing wall, with 2,9 tons/m of bearing capacity.

Load resisting stucture consists of a Special Momen Resisting Frames. In the early stages of design, the structure is designed to resist earthquake loading accordance with SNI 03-1726-2002 (Standar Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung), which is based on earthquake with return period of 500 years. Along with the adoption of SNI 03-1726-2012 (Standar Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung dan Non Gedung) which is based on earthquake with return period of 2500 years, so the calculation of earthquake loading must be redesigned. This study has an objective to make a comparison between the two codes, in terms of seismic base shear changes and examination of the structural performance of buildings in terms of drift ratio that occurs. The results of the dynamic analysis using ETASB program v.9.0.0 shows that seismic base shear increase 107% in the X and Y direction. While the results of SNI 2012 equivalent static analysis generates seismic base shear force is 2.5 times greater than the results of SNI 2002. From the requirements of drift ratio, the building structure does not exceed the requirements, according to both SNI 2002 and SNI 2012.

On the use of 5% EPS concrete compressive strength characteristics obtained amounted to 18.69 MPa (down approximately 20.9% of the normal mixture). While the use of 10% EPS, decrease concrete compressive strength of 21.67% ie 18.51 MPa. Modulus of elasticity of concrete decrease with the addition of the percentage of EPS, the use of EPS up to 40% decrease modulus of elasticity to be 16.219 MPa (down around 21%). The relationship between the modulus of elasticity (E), Specific Gravity (w c ), compressive strength (f / c ) and the percentage of EPS (p) can be expressed in an empirical equation as follows : E = (w c )1,5·0,05·exp(−0,23·p)·√f / c .
