Precast, prestressed concrete design is based on conformance with the provisions of the American Concrete Institute’s (ACI’s) Building Code Requirements for Structural Concrete (ACI 318-14) and Commentary (ACI 318R-14). In most cases, these provisions are followed explicitly. Occasionally, interpretation of some sections of ACI 318 is required to ensure quality is maintained in conjunction with the unique characteristics of precast and prestressed concrete fabrication, shipping, and erection. Members of the PCI Building Code Committee, along with other experienced precast concrete design engineers, have identified code provisions, detailed in this publication, that require clarification or interpretation. These design practices are followed by most precast concrete design engineers to produce safe, economical precast concrete structures and they provide a consistent approach for the designers and contractors.

U.S. seismic codes are undergoing profound changes as of this writing. Changes from the 1994 to the 1997 edition of the Uniform Building Code (UBC) (ICBO 1994, 1997) are many and far-reaching in their impact. The 1997 edition of the National Earthquake Hazards Reduction Program (NEHRP) Recommended Provisions for Seismic Regulations for New Buildings (BSSC 1998) contains further evolutionary changes in seismic design requirements beyond those of the 1997 UBC. The latter document will form the basis of the seismic design provisions of the first edition of the International Building Code (IBC), to be published in the spring of 2000. This paper first discusses the major changes that have been made in the concrete-related provisions from the 1994 to the 1997 edition of the UBC. The paper gives background to these changes, provides essential details on them, and indicates how they have been or how they are going to be incorporated (at times with significant modifications) into the 1997 NEHRP Provisions and the 2000 IBC. The newly published ACI 318-99, Building Code Requirements for Structural Concrete (ACI 1999), is going to be adopted by reference into the 2000 IBC. This entails further changes in concrete-related provisions beyond the 1997 UBC. Some of the more important of these changes are discussed here. A small number of amendments and additions to the ACI 318-99 provisions are going to be included in the 2000 IBC. The more important of these are also outlined in this paper.

The higher a building, the greater the burden due to lateral forces. In the planning of the building structure of Apartment 88 Avenue Surabaya, a Dual system is used. This building planning is based on the Structural Concrete Requirements for Buildings (SNI 2847: 2019). And for earthquakes based on Earthquake Resilience Planning Procedures for Building and Non- Building Structures (SNI 1726: 2019 ). In the analysis of earthquake loads using dynamic analysis of the Response Specific Trump. The structure is planned to use reinforced concrete construction. The planning method includes the primary structure, namely the dimensioning and reinforcement of the main beam, and the column. And the secondary structure which consists of dimensioning and reinforcing plates, joists. From the results obtained structural design dimensional beam 35/70 cm ( 5D22; 3D22 ), the joist 30/55 cm ( 2D16; 2D16 ), the floor slab 14 cm thick ( D10-275 )
