Abstract

Red brick is one of the materials that is still quite widely used in construction practice, because it is quite easy to get and the price is relatively cheap. Red masonry wall is a pair consisting of a binder (mortar) and a filler (red brick) known as masonry. Masonry generally provides durable construction, where the constituent material, mortar quality, and workmanship greatly affect the durability of the overall wall construction. The installation of infill walls causes the structure to become more rigid, which can sometimes cause different failure behavior between structures without infill walls and structures with infill walls. This also affects the capacity and ductility of the overall structure. Several research results show that the interaction of the infill wall with the framework is very effective in increasing the strength, stiffness, and performance of the structure in resisting lateral loads due to earthquakes. This study takes the example of a 4 (four) floor building. The analysis is carried out by modeling the walls in the SAP2000 software application, where the structural models include: Model I fully uses frame elements, Model II is a structure modeled by including infill walls without plastering as a shell element, Model III is a structure modeled using infill walls with stucco reinforcement as the shell element, and Model IV is a structure modeled using infill walls with stucco reinforcement and counter wire as the shell element. The comparison parameters in this study are structural strength and deformation. Based on the results of the analysis, Model II, 90% stiffer than the open frame structure (open frame) Model I; while Model III is 92% stiffer than Model I; and Model IV, 97% stiffer than Model I which, when viewed from the X-direction earthquake load. When viewed from the Y-direction earthquake load, the infilled frame structure for Model II is 88% stiffer than the open frame structure (open frame) Model I; while Model III is 91% stiffer than Model I; and Model IV, 99 % stiffer than Model I. Moment and latitude values ​​of Model II, Model III, Model IV are smaller than Model I both in terms of the X-direction earthquake load and the Y-direction earthquake load. Infill walls of Model II are larger than those of Model IV and Model III when viewed from the X-direction earthquake load or due to the Y-direction earthquake load. and very qualified for use in areas with high earthquake risk

Abstract

The ever-evolving construction industry demands innovation in high-quality, economical, and efficient concrete materials. Self-Compacting Concrete (SCC) is one solution due to its self-compacting ability. However, extreme conditions often affect the setting and hardening time of concrete, requiring the use of additives in the form of accelerators to accelerate or retarders to slow down the setting time. This study aims to analyze and compare the compressive strength values of SCC concrete using accelerator and retarder additives through a destructive test method. This study was conducted at the Civil Engineering Laboratory of the University of Muhammadiyah Mataram. The test specimens used were concrete cylinders measuring 15 cm x 30 cm with a design compressive strength of f’c = 20 MPa and an additive dosage of 0.5%. Fresh concrete characteristics testing included slump flow, J-ring, and sieved stability index. The compressive strength testing of hardened concrete was carried out using a Compression Testing Machine (CTM) at the ages of 7, 14, 21, and 28 days. The test results showed that the material and fresh concrete had met all the eligibility criteria for SCC concrete, with a slump flow distribution value of 65 cm, J-ring 67 cm, and a sieve stability index of 17.52%. The use of accelerator additives proved to be the most effective in increasing early strength and producing the highest compressive strength of 24,84 MPa on the 28th day. The use of retarder produced a compressive strength below normal concrete at the age of 7 days (14.60 MPa compared to 15.56 MPa), but showed a better increase in strength at the age of 28 days. Overall, the choice of additive type must be adjusted to the needs, accelerator is effective in accelerating hardening, while retarder is more suitable for improving long-term workability.

Abstract

The increasing development of the construction industry has led to a growing demand for natural aggregates, while the accumulation of non-biodegradable waste glass continues to increase, posing potential environmental problems. One effort to reduce these impacts is to utilize waste glass as a partial substitute for fine aggregate in normal concrete mixtures. This study aimed to analyze the effect of waste glass as a partial replacement for fine aggregate on the mechanical properties of normal concrete, including compressive strength and splitting tensile strength. An experimental method was employed at the Civil Engineering Laboratory of Universitas Muhammadiyah Mataram using cylindrical concrete specimens with dimensions of 100 mm × 200 mm. The waste glass substitution levels were 0%, 10%, 20%, and 30% by weight of fine aggregate. Compressive strength and splitting tensile strength tests were conducted at the age of 28 days using a Compression Testing Machine (CTM). The results showed that the average compressive strength of normal concrete was 16.22 MPa, while the concrete containing 10%, 20%, and 30% waste glass achieved average compressive strengths of 26.37 MPa, 21.74 MPa, and 20.34 MPa, respectively. The highest compressive strength was obtained at the 10% substitution level. Meanwhile, the average splitting tensile strength of normal concrete was 2.01 MPa, whereas the concrete containing 10%, 20%, and 30% waste glass produced average splitting tensile strengths of 2.99 MPa, 2.48 MPa, and 2.20 MPa, respectively. The highest splitting tensile strength was also achieved at the 10% substitution level. Based on these findings, the use of 10% waste glass as a partial replacement for fine aggregate provides the most optimal improvement in the mechanical properties of normal concrete and has the potential to serve as an environmentally friendly alternative material for sustainable construction.

Abstract

Indonesia has a high level of earthquake risk due to the interaction of active tectonic plates. This condition requires structural building planning that strictly complies with earthquake-resistant design regulations. This study aims to analyze the structural response of buildings to earthquake loads using the equivalent lateral force method based on SNI 1726:2019. The research also aims to conduct simulation and static analysis of a two-story building structure using ETABS and SAP2000 software in order to compare the results of inter-story drift, base shear calculations, and structural responses to earthquake loads. The comparison of the two software programs is intended to help verify whether the outputs, such as inter-story drift and base shear, show consistent patterns.The research method was carried out through three-dimensional structural modeling using the same parameters in both ETABS and SAP2000. Earthquake loading was calculated using the equivalent lateral force method. The results show that both software programs produce similar earthquake force distribution patterns; however, there are differences in the values of inter-story drift and base shear. The maximum inter-story drift produced by SAP2000 was 0.018055 m, while the maximum drift produced by ETABS was 0.014685 m. This indicates that SAP2000 generated a larger inter-story drift value compared to ETABS, with a percentage difference of 0.86%. Meanwhile, for the base shear values, both software programs also showed differences, where SAP2000 produced a base shear of 1753.734 kN, while ETABS produced a base shear of 1841.7433 kN. In this case, ETABS generated a larger base shear value compared to SAP2000, with a percentage difference of 0.95%. These differences are influenced by numerical assumptions and analysis parameter settings in each application. In general, the analysis results are still within the tolerance limits permitted by the standards.
