SEISMIC INDUCED STRESSES APPLICATIONS:
BY: EDUARDO H. PARE
November 2005
Adequacy of MRF RCC Frame Joints Connections Relative to Seismic Induced Stresses:
1) Even with over-designed of members sizes and reinforcements - the frame structure shall not withstand
the seismic stresses if the frame joints are inadequately applied and installed – over-sized members with
over-designed reinforcements are useless if the frame joints of the structure are not properly designed
and applied at actual installation of reinforcements. Installation of bars at frame joints are one of the most
common mistakes and negligence during actual construction works which shall result to failure and
collapse of the structure in an earthquake.
2) Proper applications of construction joints at frame joints of the structure are of utmost importance to
consider so that the building shall have adequate sustainable resistance during occurrence of an
earthquake – incorrect applications at site of the frame joints construction joints shall result to diminish
the frame joints adequacy of the structure against seismic induced stresses – proper locations and
applications of construction joints relative to the assumed designed of the frame joints of the structure
shall be properly applied on actual construction works. These applications of proper constructions joints
at frame joints of the structure are one of the common mistakes and negligence on actual construction
works of the building which shall result in subsequent failure and collapse of the building in an earthquake.
3) Incorrect applications of lap lengths, curtailments of bars, anchorage lengths, etc. of members
reinforcements shall also results in diminishing the structural strength of the frame structure. Correct bars
lengths and curtailments of bars are required so that members strength shall be attained against seismic
stresses at frame joints and along the members of the structure – these bars lengths and curtailments are
also common mistakes and negligence during construction works of the building.

5. THE 10 METHODS OF DESIGNS AND ACTUAL CONSTRUCTION APPLICATIONS OF CONCRETE STRUCTURES
TO AVOID WATER LEAKAGES ON BUILDING:
BY: EDUARDO H. PARE
November 2004
1) Proper design of concrete mix shall be achieved and applied on site application - i.e. concrete
aggregates and cement contents, and water/cement ratio shall be strictly in adherence with the Code but
with considerations on actual local conditions and type of materials to be used.
2) Proper workmanship of concrete shall be applied onto the works - i.e. proper actual conveyance and
placement of concrete including correct actual applications of electrical and manual vibrations on fresh
concrete substrates shall be applied, honeycombing due to aggregates segregation shall also be avoided.
3) Proper concrete covers as required by the Code for which a structure was designed with, shall also be
strictly implemented onto the works since hypothetically if the minimum concrete cover is not applied or
it was not actually properly applied on each every aspect of the structure, it will affect the crack width
constrains and the overall functions and resistance of the concrete elements since concrete is an element
from within its own elements - i.e. fibers of concrete shall also be analyzed on each millimeter of directions
and movements, etc.
4) Minimum and maximum spacing of reinforcements shall be applied on each aspect or member of the
structure since shrinkages, creeps, thermal hydrations, and other concrete service stresses shall affect the
crack resistance of concrete on each pre-construction, post-construction, and occupancy activities and
periods of the structure/building.
5) Proper curing shall be applied on each aspect of the structures elements which shall include the
minimum time required for formworks and scaffoldings/struts to be removed - I do not agree with early
removal of forms then installing back the struts or vertical supports since even within few minutes of
removal then reinstalling - it shall surely affect the short term deflections of concrete elements relative to
the correct removal period of the same.
6) Though structural members and foundations are (hypothetically) designed within crack width
constrains stipulated in the Codes, as much as possible construction joints shall be avoided during
construction works on floors of the building, if construction joints are indeed required, such joints shall
be redesigned with provision of a least size but wider beam underneath the joints which shall serve to
have key grooved joint along such CJ beam.
7) It is technically incorrect to provide construction, movement or expansion joints on basement
slab/foundation and walls - which shall affect the water tightness of the structure. Foundations and walls
reinforcements shall be designed and detailed to have adequate quantities and spacing to not only resist
the design forces and stresses but including crack resistance requirements as specified in the Codes.
8) As much as possible no lateral embedments of electrical conduits, drainage pipes, and other utilities
elements casted inside the slabs and beams on floors - only vertical services sleeves and lines shall
penetrate the floors, since these lateral penetrations of utilities elements are one of main culprits on
water leakages on floors of buildings. These lateral penetrations particularly when they are in sets or in
groups of parallel rows just like bundled conduits and pipes inside floor slabs and beams shall create cracks
no matter how dense the spacing of reinforcements since concrete areas diminished in these lines.
9) Cold joints shall be avoided during concrete casting on floors - the ideal maximum time for the next
stage of concrete to join or connect with previous stage or module of concrete shall be 45 minutes or less.
10) If the Ready mix Supplier is in your doubt or is not reliable - conduct actual mock up sample of the
design mixes to come up with a cured-finished piece of module and tested it against water ingress prior
to actual pouring of concrete onto the floors of the building.

6. PARTICULAR CONSIDERATION ON ANALYSIS AND DESIGN OF STRUCTURE TO AVOID WATER LEAKAGES
ON BUILDING:
BY: EDUARDO H. PARE
November 2004
It shall also be noted that the structure and its foundation shall also be properly analyzed and designed
with correct assumptive applications of short and long term settlements including differential settlement
since such stresses resulting from these induced settlements shall affect the joints stiffness resistance of
the structure which can result in diminishing the designed capacity and resistance of each member of the
structure and of which then shall create cracks and deflections or movements at such lines or locations of
settlements stresses.
If the above specified procedures on design and construction applications of concrete structures are
properly applied in the design processes and construction works of RCC frame structures, waterproofing
proprietary products are indeed not required in controlling water ingress onto concrete elements - the
elemental concrete substrates of the RCC structures shall attain their own internal waterproofing and
damp proofing resistance - though concrete elements are hypothetically assumed as nominally having
porous internal fibers, and of which a substantial cost savings on waterproofing products applications and
maintenance works are foreseen - and these procedures and actual resulted applications were actually
proven effective and applicable on design and construction works of my RCC frame structure 600 square
meter floor area residence - and such procedures and applications are actually still currently effective and
applicable many years from occupancy period of my own all-concrete residence.

7. THE DESIGN AND ASSUMPTIVE LIFE SPAN OF BUILDING:
BY: EDUARDO H. PARE
November 2004
The Life Span of Building depends mainly on its designed strengths, capacities, and functions, it also
depends on its type of materials, and its built-in location:
1) Building structural frame system shall be designed to withstand and resist without deformations and
failures cyclic nominal static (gravity) and presumed assumptive dynamic (seismic) loads, and other forces
of natures such as winds and downpours, volcanic eruptions, sinking holes underneath, etc.. Buildings
built on locations without movements of soil strata underneath can expect to reach or actually surpassed
their life span as in the case of buildings or structures still standing in modern times after many or
hundreds of years thereafter - and though without the modern bars or steel reinforcements, however
owing to non-existence of lateral and dynamics forces, such building which are mainly built of natural
materials of bricks, clay, limes, boulders, etc., indeed are still alive and kicking since their frame structures
are tri-axially motionless in nature and therefore shall suffice to support and hold-in-place reactionary
compression (only) forces onto it.
2) In addition to proper designs of their strengths, capacities, and functions relative to the requirements
as specified on relevant applicable Building Codes where such buildings are subjected with, and as such
for buildings being built on locations with static coupled with dynamic natures forces as mentioned (1)
above - proper corrosion controlled applications of the structural members and their bases and
foundations shall be applied - corrosion is one of main culprits that holds the key for the life span of
buildings - uncontrolled corrosion shall shorten the design or intended life span of buildings, on the other
way - controlled corrosion shall foresee the building to reach or actually surpassed its design or intended
applied life span. Since corroded reinforcements and steel elements can be equate hypothetically to
failure of the building.

8. SEISMIC VERTICAL AND HORIZONTAL INDUCED COMPONENTS RELATIVE TO ITS EPICENTER AND RADIAL
DISTANCE RANGE:
BY: EDUARDO H. PARE
November 2005
Based from past earthquakes occurrence data, tests, and analyses conducted and established in some
countries, it was hypothetically concluded that the vertical component of earthquake is in the common
range of 1/2 to 2/3 of the horizontal component for a radial distance of longer than 25km from its
epicenter which is also the assumed fault line origin, however the vertical component of the earthquake
ground motion is greater than unity and is increasing - which can even reach double the horizontal
component when calculating earthquake forces within the 5km to 20km radial distance from its
epicenter/fault line origin. It is therefore imperative to analyze and confirm the proper location of the
proposed structure (to be designed) relative to the radial distance from the established (assumed) fault
lines to at least use the nearest correct parameter for the earthquake vertical component factor.

EFFECTS OF COVERS AND BAR SPACINGS ON ADEQUACY OF FRAME JOINTS OF THE STRUCTURE AGAINST
INDUCED SEISMIC STRESSES
BY: EDUARDO H. PARE
November 2002
Proper applications of concrete covers and adequate bars spacing shall be applied on the building
structure particularly at frame joints of the structure since without correct applications of concrete covers
and bars spacing (for the smooth flowing of concrete) - shall render the reinforcements hypothetically
useless at such joints and shall results to subsequent failure and collapse of the building during occurrence
of an earthquake – some thought that concrete covers are of minor importance to consider, and such
shall result to grave mistakes accordingly since bars without the proper covers shall not contribute to
attain the hypothetical functions and strengths of reinforced concrete - i.e. the tensile and compression
coupling equilibrium, of which then shall result to make the member function as (only) plain concrete
element though bars are actually installed at site onto the structural frame system.
