Venezuela Standards for Structural and Seismic Design

Venezuela Standards for Structural and Seismic Design
VENEZUELA - LRFD steel design code
This Standard provides the criteria and minimum requirements for the design, manufacture, assembly, construction, inspection and maintenance of steel structures and steel composite structures - concrete buildings, as well as that of its members, components, joints and connections, which are planned or implemented in the country, and be applied in conjunction with the Venezuelan Standards and COVENIN -MINDUR. This standard applies to both new buildings and the evaluation, adaptation, rehabilitation, strengthening or repair of existing buildings that meet the requirements of Venezuelan COVENIN - Building Seismic MINDUR 1756-1998. Temporary or interim work must also comply with the provisions of this standard.Excluding the domain of application of this Standard: hollow sections, cold formed profiles and open web joists (joists), which are governed by specific rules. See transitional provisions. The term structural steel used in this Standard refers to any member or element described in the contract documents as such and / or the need for strength and stability of the structure. These members and structural steel elements are listed in general terms in COVENIN - Standardized MINDUR 1755 Code for the Construction and Steel Structures practices.

The notation used in this standard essentially corresponds to that contained in the Standards of the American Institute of Steel Construction, AISC, especially AISC-LRFD 1993 standard. The system corresponds to MKS units: meter (m), Kilogram force (kgf), Second (s). 

VENEZUELA - Design and construction of structural concrete code
This code establishes requirements for the design and implementation of structural concrete buildings that are planned or built in the country. Applies to all aspects of the design, construction, inspection, supervision, maintenance, evaluation, adjustment or repair, as well as the properties and quality assurance of materials. Temporary or interim work must comply with the provisions of this standard.Where appropriate, this Statement or any part thereof, is applied to the design, construction, inspection, monitoring and maintenance of structures for silos, grain elevators, warehouses, structures explosives testing, and other civil works, without prejudice to other specific technical criteria for the purposes of each work. Excluded from this standard:
The concrete with less than 1400 kgf / m3 unit weights.
The concrete with higher compressive strength specified in 600 kgf / cm2.
Members exposed to temperatures above 100 ° C.
The structures or members pre or post-tensioned concrete.
Structural systems consisting of prefabricated members.

The concrete used in mixed steel-concrete constructions comply with the provisions of this standard. Mixed steel-concrete members not included in this Statement are subject to the Venezuelan Standard 1618. Included within the scope of this standard the following members of steel-concrete composite structures: Mixed steel-concrete columns when the area structural steel profile is less than 4% of the total area of the mixed column. See Article 10.7. Concrete slabs emptied on sheets of corrugated metal (metal soffit) designed and built without considering joint action steel - concrete. See Chapter 16.

In addition to the general requirements of the particular project in this Standard, the buildings must comply with the special provisions for earthquake resistant design according to the design level. Levels of Design, ND, required in different seismic zones are set out in standard Covenin 1756.

This code is based on the Building Code Requirements for Structural Concrete (ACI 318-05) and Commentary (ACI 318R-05) of the American Concrete Institute with the amendments that were considered appropriate to adapt to our environment. Unlike the existing 318 ACI Code, the requirements of earthquake-resistant design are integrated in all the articles. This is reflected in Chapter 18, which is now more rational system. This aspect is also reflected in the design of foundations, which is in Chapter 15.

The units used in this Standard for the Technical System MKS, Metro-Kilogram-force Segundo, predominantly used the kilogram-force (kgf) and centimeter (cm) and combinations thereof; It is indicated in parentheses, the corresponding unit in the International System of Units SI.

VENEZUELA - Criteria and minimum action code
Every building and every one of its parts should have the strength, rigidity and stability necessary to perform satisfactorily and safely to limit states that may arise during its lifetime. Consequently, the architectural project will enable efficient structure to resist any measures that may affect the building, with particular attention to seismic activity. In addition, special care will be taken in the light bracing buildings.These standards establish the criteria and minimum requirements for the actions to be considered in the design, manufacture, assembly and construction of buildings that run in the country. These rules will apply to new buildings and to the modification, extension, reinforcement, repair and demolition of existing buildings both. Temporary or interim work must also comply with these provisions.

As appropriate, these Rules shall apply in the draft other structures such as bridges, silos, grain elevators, tanks, reservoirs, etc., provided they do not conflict with specific technical standards and criteria for action on such constructions . In buildings that use non-traditional building systems in addition to the actions set forth herein, shall be taken into account that particular system were used.

The actions defined here are the service or use, apply both classical theory and the theory of limit states.

VENEZUELA - Wind actions on structures code
COVENIN codes establishing minimum requirements for the determination of wind actions on buildings that are planned or implemented in the country (Venezuela). Require appropriate criteria for quantifying the main effects that cause the wind on the types of construction that are specified therein. They apply to the calculation of wind actions on structural systems, individual structural components and materials that constitute the walls of buildings.Concepts and Limitations: The standards are minimum requirements for the effects of wind on new buildings and related structures and components. Wind effects defined in the standard are considered service loads.

Performance Objectives: Not considered explicitly.
