Abstract
Indonesia is prone to earthquakes, many „engineered‟ buildings have been damaged and collapsed causing many casualties due to misplaced planning. Therefore, a good cooperation between architects and structural experts is urgently necessary to prevent this problem. Hence, the earthquake architecture is created. By means of the design process, architects can identify and evaluate the vulnerability of building to the earthquake. Unfortunately, there is no evaluation method; thus, the alternative is adapting SVA (Simplified Vulnerability Assessment) method which is a limited engineering analysis based on information from architectural drawing and structure in existing building. The Japan Building Disaster Prevention Association (JBDPA) and Matsutaro Seki developed SVA. Seki modifies SVA of JBDPA and adapts it to international earthquake regulations. However, both SVA methods are used to evaluate the vulnerability of existing building to the earthquake for retrofit purposes. Meanwhile, the SVA method for architectural design purposes up to now does not yet exist. Novelty from this research is the adaptation of retrofit method SVA of JBDPA and Seki become SVA Architectural Design which will be suitable for the construction condition in Indonesia. In an effort to answer the purpose of this research is to build procedures or methods that can be used by architects in evaluating the vulnerability of building to the earthquake in the process of architectural design in accordance with the condition of Indonesia. Having obtained the SVA method of Architectural Design, the results of this adaptation are validated and used to evaluate the vulnerability of existing buildings in Semarang as one of the most earthquake-prone cities in Java Island. The result is the weakness of the design of the earthquake made its guidance. This research is a quantitative research with case study method. The validity and reliability test of the SVA Method of Architectural Design was conducted with non-parametric test of Wilcoxon Two-Related-Samples and Spearman correlation with 10 pushover analysis results from other researchers. From these two tests, the results are good enough to predict the potential vulnerability of building to the earthquake in the process of architectural design and consistency of the results of the analysis is considered quite good. SVA JBDPA and Seki, in the principle, is a safe structure if the earthquake the seismic structure index ≥ the seismic demand index. The adaptation of retrofit SVA of JBDPA and Seki into SVA of Architectural Design in this research is that the seismic structure index is basic seismic structure index and irregularity index. Variables in the basic seismic structure index were adopted from the theory of “Rapid Evaluation of Earthquake Resistant Frame Resistance System according to SNI 03-2847-2002 and SNI 03-1726-2002”. The basic seismic structure index consists of variables : column and/or shear wall dimension index, column and/or shear wall stiffness index, strong column/weak beam index, redundancy index, and structure ductility index. The irregularity index variables were adopted from the “Horizontal and Vertical Structural Irregularities” theory of FEMA 451B. Meanwhile, the seismic demand index is the multiplication of seismic response index and the main function factor of the building. From the result of adaptation of retrofit method SVA of JBDPA and Seki to be SVA of Architectural Design as described above, 2 findings were obtained in this research that is the method of vulnerability evaluation of structure of moment frame for earthquake and the method of vulnerability evaluation of structure of moment frame and shear wall for earthquake. After the SVA Design Architecture method was obtained and validated Wilcoxon Two-Related-Samples Test with 10 results of vi pushover analysis with a good result. The advantage of SVA Architectural Design is that it has the ability to approach pushover vulnerability analysis compared to RVS (Rapid Visual Assessment), retrofit SVA of JBDPA and SVA Seki. Particularly, it has the more complete quarantine earthquake resistance evaluation criteria in relation to the preliminary design of building structures and the evaluation criteria for regular/irregular geometry in relation to the exploration of the building form design. Furthermore, the SVA Architectural Design was applied to evaluate the vulnerability of 8 existing building plans in Semarang coming from the Building Permit of Spatial Planning Department of Semarang City. Semarang City was chosen because it is one of the 3 most earthquake-prone cities in Java Island. From the evaluation, the results obtained are the design weaknesses, and from the weaknesses, the guidance was made with the process of finding more earthquake resistant form; setting the dimensions of the beam/column and the severity of the columns based on the strong column-weak beam concept; overcoming short columns with window settings and overcoming slender columns with settings in building structures; setting the location of the shear wall in the regular form based on the rigidity of structure, mechanical electrical and circulation; overcoming the irregularity of re-entrant corners with dilatation and shear wall arrangements; overcoming weight/mass irregularity and vertical geometry with preliminary arrangement of cantilever beam dimensions; overcoming the weak story by setting the gradual or evenly shifting shear wall dimensions; and overcoming the soft story due to differences in the density of brick walls. From the guidance process, there are other findings, namely the formula for determining the width and height of different column dimensions based on the ratio of the module structure and the determination of the same column width and height dimensions based on the graph of column dimension relationships and structural modules. Then the two findings were tested for validity by the Wilcoxon Two-Independent-Samples test with the results of the two findings of good validity and from the Spearman correlation reliability test both of these findings are also very good consistency.
