In the numerical modeling presented, the deep beam is accounted for by means of a three dimensional FEA ANSYS 13.0 approach, in which the structure is modeled with load-displacement-based solid finite elements, whereas the internal work structure interacted by high strength concrete and reinforcement in full scale. Most deep beam collapse is dominated by the shear brittle collapse. Recently, confinement is the most effective way to improve the ductility of the reinforced concrete, whereas required to anticipate the occurrence of direct crack on the beam caused by quite large shear forces. Numerical models of deep beam with high strength concrete is done gradually by giving a variation of concrete strength, confinement and stirrup spacing. The two point load are applied with the ultimate load on all models. Then, analyzing of the deep beam is to be done with and without side reinforcement and also an analysis of the crack pattern of the beam to calculate the brittle area under the ratio of crack volume occurred. Concrete is modeled by SOLID65 and steel reinforcement using SOLID45 element. The collapses occurred are all ultimate flexural compressive collapse on the loading plate area, due to brittle shear collapse. The condition occurred on deep beam first crack was already considered a collapse, the density of reinforcement and the additional distance comprehensive reinforcement bar is most effective in terms of adding high ductility of high strength concrete beams. By using the stirrup reinforcement with confinement mode can significantly enhance the resistance of ultimate capacity, cracking ratio and reduced deflection.

The objective of this paper is to perform the design practice for the structures of stilt building construction, based on the seismic design methodology. Firstly, the design requirements and design constraints are determined according to the site of the building within the Banjarmasin city of the wetlands area and compared with the other zones. Based on the latest Indonesia earthquake design code, the city of Banjarmasin is in the lightest earthquake hazard area so it is considered to neglect the seismic load in earthquake resistance. Actually, South Kalimantan region, mostly as wetland area, has experienced earthquakes several times. On the entire area, the land has a soft soil condition which has the potential to damage buildings in the event of an earthquake due to the amplification of earthquake vibrations. Then, a practical design chart of the basic earthquake load response spectrum has been analyzed. Apart from that, a design practice of varying soil strata is generally considered by the latest code for earthquake engineering design SNI-1726SNI- -2019 The results indicate that the earthquake response spectrum design charts for all areas in the low risk zone, as the soft soil ground strata, affected into the seismic load design of earthquake force should be taking into account for design practice. The base shear for the stilt structure of multy story building should be designed as approximately one thirteith of total weight of the building structure.

The column is a critical element in the building structure, the failure of the column will directly result in the collapse of other related structural components. The column must have strength, stability and ductility. In increasing the capacity and ductility of the column by providing confinement, to protect concrete elements from breaking due to the influence of the working pressure. Analyzing ultimate axial load capability, stress-strain distribution patterns and crack patterns in concrete elements and column ductility. Tests of several models and variations of the restraint distance in short columns of normal concrete quality with longitudinal reinforcement of steel steels and carbon steel transversal reinforcement. The columns were analyzed using the Finite Element Analysis (FEA) method with the help of a full scale ANSYS 3-D application, with material properties for concrete using SOLID65 and steel reinforcement using LINK8 and SOLID45 loading plates. The type of pedestal used is the joints with axial loading (axial loadstep) centric direction. The effect of the restraint model and the variation of the restraint distance to the value of the column ultimate axial load for the whole model is relatively small with a ratio of 1.079, while for the ratio of the axial deformation ratio of 1.496. The pattern of stress and strain distribution when yielding spreads throughout the column area but when it reaches the ultimate distribution the concentration is concentrated in the support area. The first dominant crack occurs in the pedestal area and generally occurs in the concrete blanket layer, in the ultimate condition cracks have occurred evenly throughout the column area. The ratio of the ratio of ductility values ??for all column models and the restraint distance is relatively large with a ratio value of 1.523
